Resin ya Vinyl Ester: Icyo imyaka 35 mu mwobo yanyigishije ku bijyanye no kuyishakira isoko neza

Kuva mu 1989, maze imyaka 35 nkora imashini zikora ibintu bitandukanye, nkoresha styrene, nkoresha intoki zanjye kuri laminate ishyushya, kandi nkorana n'abatanga serivisi basezeranya isi kandi bohereza imyanda. Niba urimo gusoma ibi, birashoboka ko ukeneyeresin ya ester ya vinylku kintu cy'ingenzi. Ikigega cy'imiti. Ubwato. Umuyoboro w'amazi. Ngiye kubabwira icyo nize ku bijyanye no gushakautanga resini ya vinyl ester utazangiza umushinga wawe. Mfite ibitekerezo. Sinzabigabanya.

Reka kuvanga Vinyl Ester na Polyester

Resin ya ester ya vinylni mubyara wa epoxy. Ufata umugongo wa epoxy ukawuhuza na aside methacrylic. Amatsinda ya ester arangira ku mpera z'uruhererekane gusa. Ubwo ni bwo buhanga bwose bwa molekile. Amatsinda make ya ester bivuze ko aside na alkali ari bike.

Polyester ifite amatsinda ya ester ku ruhererekane rwose. Niyo mpamvu ibigega bya polyester bicika nyuma y'imyaka itanu bikoreshwa mu buvuzi bwa shimi. Ibigega bya ester bya vinyl bimaze imyaka makumyabiri. Nabishyizemo byombi. Itandukaniro ntabwo rigaragara.

Narebye abaguzi bambaye polyester isophthalique kuko "iri hafi bihagije." Ntabwo iri hafi bihagije. Isophthalique ni resin nziza. Ntabwo ariresin ya ester ya vinylNiba umukiriya wawe yaguze ester ya vinyl hanyuma ukamwohereza polyester ya iso, uzafatwa. Ikizamini cya laboratwari kimara iminota cumi n'itanu. Hanyuma izina ryawe rigaragara kuri raporo y'ibyananiranye. Ntubikore.

Epoxy irusha ester ya vinyl ku mpapuro. Mu by'ukuri, epoxy igura kabiri, ikenera ifuru imaze gushya, kandi laminators zawe ntizizakunda kuyikoresha.Resin ya ester ya vinylibikorwa bisa nka polyester. Ushobora kubishyiraho n'intoki, kubitera, kubitera, no kubikoresha muri RTM. Ubwo buryo bworoshye bwo kubitunganya niyo mpamvuresin ya ester ya vinylIfite agaciro ku isoko ryo hagati mu rwego rwo kwangirika. Epoxy ifite indege. Polyester ifite ibintu bihendutse. Ester ya vinyl ifite byose biri hagati.

Ikiganiro ku giciro ntawe wifuza kugira mu by'ukuri

Dore icyouruganda rukora resin ya vinyl esterMu by’ukuri yishyuza. Ester ya bisphenol-A isanzwe ikoresha 2,800 kugeza 3,500 kuri toni. Ester ya Novolac epoxy vinyl — ifite ubushyuhe bwinshi — iri hagati ya 3,800 na 4,500. Epoxy itangirira kuri 4,500 ikarenga 7,000. Polyester ya Ortho iri munsi ya $1,800.

Resin ya ester ya vinylibiciro byikubye kabiri ugereranyije n'ibiciro bya polyester ya iso.

Ariko muri aside sulfuriki 30%, ester ya vinyl imara igihe kirekire inshuro eshatu kugeza kuri eshanu.

Nakuyemo ibice by'umubiri mu kigega cy'imiti umwaka ushize. Imyaka cumi n'itanu maze nkora. Ikanzu ya vinyl ester yari ikiri nzima. Ikigega kimwe, ikanzu ya polyester backup, imiterere yacyo ni imwe. Nashoboraga gusenya iyo resin ya polyester nkoresheje igikumwe n'urutoki rwanjye.

Rero iyo umuyobozi ushinzwe amasoko ambwiye ko ester ya vinyl ihenze cyane, nibaza ikibazo kimwe. Ikigega gitwara iki iyo cyananiwe? Isuku y'ibidukikije yonyine igura inshuro icumi z'ikiguzi cya resin. Urubanza ruri hejuru. Imibare ni yoroshye. Abantu ntibashaka kubikora kuko umubare w'inyuma usa n'aho ari munini kuri PO.

Icyizautanga resini ya vinyl esterigufasha kubaka ako gasanduku k'ubuzima. Ikagutwara nabi igura igiciro cya kilo imwe hanyuma ikazimira.

Umucuruzi cyangwa Umukora — Menya Gutandukanya

Kimwe cya kabiri cy'ibigo biri kuri platform za B2B byiyita "utanga resini ya vinyl ester"Ni abacuruzi. Nta rektora bafite. Nta laboratwari bafite. Bagura mu ruganda rugura epoxy mu rundi ruganda. Resin igaragara ku cyambu cyawe ifite imibare idahuye na CoA. Ubushyuhe bwagabanutseho 40%. Urahamagara kugira ngo winubire. Nta muntu ukira.

Dore uburyo bwo kubikuraho vuba.

Saba amafoto ya reactor ariho itariki iriho ku rupapuro ruri ku ifoto. Saba umusaruro wa buri kwezi muri toni za metric. Saba CoAs kuva mu byiciro bitatu bikurikirana. Ishusho nyayouruganda rukora resin ya vinyl esterasubiza ibi bibazo ako kanya. Umucuruzi aravuga ati “reka ngusuzume hanyuma ngusubize.” Iyo nteruro ikubwira byose.

Nasuye "umukozi" mu 2019 wari ufite urubuga rwiza rwerekana icyumba cy'imashini ikora ibikoresho by'amashanyarazi. Naje imbonankubone. Icyo kigo cyari ububiko bufite ingoma zanditseho amazina. Nta mashini ikora ibikoresho by'amashanyarazi. Nta laboratwari. Hari umuntu umwe ufite telefoni. Narasohotse. Uwo twari duhanganye ntiyayibonye. Yatakaje $80.000 kubera ikintu kibi cyavuye mu ngoma mu gihe cyo kohereza. "Umucuruzi" yafunze nimero ye.

Imitungo Ifite Ireme ku Iduka, Ntabwo Iri ku Gatabo

Sinitaye ku rupapuro rw'amakuru. Nshishikajwe n'uko bigenda iyo resin ikubise ku ibumba.

Ubushyuhe. Niba iri hejuru ya mPa·s 500 kuri 25°C, laminators zawe zizarwanya ubushuhe buturutse ku mazi. Zizayigabanya na styrene. Noneho wagabanyije resin. Imiterere iragabanuka. Umutanga aragushinja kongeramo styrene. Urashinja umutanga ko yohereje resin nini. Narebye iyi ngingo ibaho inshuro ijana. Gukemura ikibazo biroroshye. Gura kuriuruganda rukora resin ya vinyl esterugenzura ubushyuhe buri hagati ya mPa 200 na 400. Buri gihe.

Igihe cya jeli. Nakoresheje itsinda rimwe rya jeli mu minota 12 ku bushyuhe bwa dogere selisiyusi 35. Iminota cumi n'ibiri. Ntushobora gushyiraho icyuma gifata intoki mu minota cumi n'ibiri. Ukeneye iminota 25 kugeza kuri 40 yo gukora akazi gakomeye ko gushyiramo intoki.utanga resini ya vinyl esterUgomba guhindura ipaki ya promoter kugira ngo ihuze n'iduka ryawe. Cobalt naphthenate nyinshi ku maduka akonje. Gake ku ashyushye. BPO niba urimo gushyushya munsi ya 15°C. Niba umucuruzi adashobora guhindura sisitemu yo gushyushya, arimo kugurisha formula idahinduka kandi yiteze ko uzayikoresha. Ibyo ni ibyahindutse. Resin irakora kuri wewe. Ntabwo ukorera resin.

Ubukana bwa Barcol. Igomba kugera kuri dogere 35 kugeza kuri 40 mu masaha 24 ku bushyuhe bw'icyumba. Iyo ihagaze kuri dogere 28 nyuma y'iminsi ibiri bivuze ko hari ikibazo. Ijanisha rya MEKP ryagabanutse, cyangwa resin ishaje, cyangwa promoter yangiritse kubera kubika nabi. Nabonye resin "nshya" yari imaze amezi cumi n'umunani kuko yari iri mu bubiko bushyushye bw'umucuruzi. Promoter yari imaze gutangira gukora imbere mu gikombe. Ubona imiti idakora neza kandi ubuso butoshye butajya bukomera neza.

Aho nabonye Vinyl Ester Itsinda — n'aho abantu bapfusha ubusa amafaranga

Navuzeresin ya ester ya vinylku bigega byo kubikamo imiti, imiyoboro y'amazi, ibyuma byo mu mazi, imiyoboro itwikiriwe, n'imiterere y'inyubako yangiritse. Irakora neza. Ikora neza cyane mu buryo bwo kwangiza no ahantu hose ukeneye igishushanyo mbonera cy'imyaka 20.

Ibimera bya shimi. Icyo ni cyo gikomeye.Resin ya ester ya vinylni cyo gikoresho gisanzwe cyo kubikamo ibintu bya kabiri. Niba urimo kubaka ikigega gifata aside hydrochloric 30%, nta bundi buryo buhendutse bushobora kubaho. Ndabivuga neza.

Marine. Amazi y'umunyu arya polyester. Ester ya vinyl igumaho imyaka ibarirwa muri za mirongo. Abubatsi b'ubwato b'abahanga bakoresha ester ya vinyl ku ruhu rwo hanze ruri munsi y'umuyoboro w'amazi maze bagahindura polyester kugira ngo bakore imiterere y'imbere. Ubona uruzitiro rw'ingufu aho uzikeneye. Uzigama amafaranga aho utazigamye.

Ariko aha niho birambirana. Nabonye injeniyeri zikoresha ester ya vinyl mu kigega cy'amazi ku bushyuhe bw'ikirere. Amazi. Ubushyuhe bw'icyumba. Polyester ya Iso ibikoraho imyaka makumyabiri ku giciro cya kabiri. Ibi mbibwira abakiriya nubwo byaba bivuze ko ngurisha resin nkeya. Iyo urenze urugero, uba upfusha ubusa amafaranga y'umukiriya wawe. Amaherezo barabimenya bagashaka umuntu uzababwiza ukuri.

Ububiko Buzakwica Inyungu Yawe

Resin ya ester ya vinylifite igihe cyo kubikamo amazi kuva ku mezi 3 kugeza kuri 6 kuri 25°C. Buri dogere selisiyusi 10 hejuru yayo igabanya igihe cyo kubikamo amazi mo kabiri.

Nabonye abaguzi batumiza kontineri yuzuye, bakayiparika mu bubiko bw'icyuma muri Nyakanga, maze nibaza impamvu resin yashyizwe mu ngoma nyuma y'ibyumweru umunani. Ubushyuhe bwica ester ya vinyl. Promoter itangira kugira icyo ikora. Ubushyuhe burazamuka. Umunsi umwe mu gitondo ufungura ingoma irakomera.

Nibautanga resini ya vinyl esterKohereza ibicuruzwa biva mu mahanga, utakaza ibyumweru 3 kugeza kuri 4 byo kubikwa mu modoka. Gasutamo irarya ikindi cyumweru. Ububiko bwawe bugumaho ukwezi kose. Ushobora kuba usigaranye ibyumweru bitandatu byo gukoresha iyo ufunguye ingoma ya mbere.

Gutumiza ingano ntoya kenshi. Igiciro cya kilo kirazamuka gato. Ujugunya resin nke cyane. Nahinduye umukiriya kuva ku gutwara amato menshi ajya ku mato ya IBC ya buri kwezi. Imyanda ye yagabanutse kuva kuri 12% igera munsi ya 2%. Imibare yaragenze neza.

Impamyabushobozi si amahitamo

ISO 9001 ni yo ngingo. Nibauruganda rukora resin ya vinyl esterntibyifashe, hagarika ikiganiro.

Kohereza i Burayi? Ukeneye kwiyandikisha kuri REACH. Nta REACH, nta ruhushya rwa gasutamo. Narebye kontineri yose y'umukiriya ifungiye i Rotterdam mu gihe cy'ibyumweru bitatu. Resin yabuze ibyangombwa bya REACH. Amafaranga ya Demurrage yarenze agaciro ka resin. Umucuruzi yashyize amaboko hejuru.

Porogaramu zo mu mazi zikeneye kwemezwa na DNV cyangwa ABS. Amanota adakoresha umuriro akeneye UL 94 V-0. Genzura neza ko icyemezo gikubiyemo amanota runaka urimo kugura. Nafashe abatanga serivisi bagaragaza icyemezo cya UL ku wundi murongo w'ibicuruzwa kandi nizeye ko ntazabibona. Nabibonye.

Icyo mbwira buri mukiriya mushya

Shakauruganda rukora resin ya vinyl esterupima buri gice cy'ibinyabutabire hanyuma akohereza CoA mbere yuko ubaza. Umuganga w'imiti ku bakozi agomba gusubiza telefoni igihe resin yawe idakira. Gupakira bigomba kumara ibyumweru bitatu mu gikoresho. Inyandiko zigomba kuboneka mbere yuko uyikurikirana.

Teganya mbere na mbere. Buri gihe. Toni imwe kugeza kuri eshanu. Inyuze mu murongo w'umusaruro wawe. Si laboratwari. Laboratwari ni ibinyoma. Aho iduka rikorera niho havuga ukuri. Andika igihe cya jeli ku bushyuhe bw'iduka ryawe. Reba igihe amazi yavuye ku bushyuhe bwawe. Shaka igihe cyo gukoresha. Shaka aho pinholes na fish-eyes biri ku buso bwa gelcoat.

Noneho gereranya imbonankubone n'icyo urimo gukoresha ubu. Niba resin nshya ikira vuba, ikanyoha neza, kandi ubuso busukuye, wabonye uwagutanga. Niba hari kimwe muri ibyo bintu kibi kurushaho, komeza ushake.

Nakoranye naabatanga resini ya ester ya vinyluturutse mu Bushinwa, mu Buhinde, mu Burayi no muri Amerika. Ibyiza biri hose. Ubuso bw'isi ntabwo bugena ubuziranenge. Igenzura ry'imikorere rigena ubuziranenge. Uruganda rukora neza i Shandong rutsinze ibikorwa bidakora neza i Stuttgart. Nabibonye byombi.

Resin ihendutse ntabwo ari resin ihendutse cyane. Nabimenye mu 1997. Nayishyuye nkoresheje ikigega cyangiritse n'umukiriya urakaye cyane. Isomo ntiryahindutse mu myaka 28 ishize. Ntukabyige nk'uko nabyize.
