Kora ubu ukoresheje DDI (Dimeryl Diisocyanate) CAS NO. 68239-06-5 ku miti ya polyurethane idafata amazi

Akenshi ubona ko amazi ashobora kwangirika bitewe n’amazi bitera ibibazo mu irangi rya polyurethane. Ibikoresho byinshi bigaragaza inguni nke zihuza amazi, nk'icyuma kitagira umugese kuri dogere 76.3, polyurethane igenzura kuri dogere 95.2, hamwe n'irangi rya polyurethane rirwanya udukoko riri munsi ya dogere 83. DDI (Dimeryl Diisocyanate) CAS NO. 68239-06-5 ikuraho ibi bibazo. Imiterere yayo yihariye igufasha gukora ibikoresho bya polyurethane bidafata amazi kandi biramba.

Ibintu by'ingenzi byakunzwe

• DDI (Dimeryl Diisocyanate) ikora polyurethane idafata amazi irwanya ubushuhe, bigatuma iramba kandi iramba mu bikorwa bitandukanye.
• Gukoresha OYA kunoza imikorere y'ibicuruzwa bya polyurethane binyuze mu kugabanya ibibazo nko kuzana uduheri no kunanirwa kwangirika kw'amazi, bigatanga umusaruro wizewe.
• Guhuza OYA Gukoresha ingano y'imiti yawe biroroshye: hitamo polyol ikwiye, uvange mu buryo bugenzurwa, hanyuma ugerageze niba amazi adashobora kuyinywa kugira ngo ubone umusaruro mwiza.

Ubushobozi bwo kuvura amazi muri Polyurethanes

Ibisobanuro n'ingaruka

Ubuhanga mu by'amazi bugira ingaruka ku mikorere n'uburyo ibikoresho bya polyurethane bikora. Iyo ukoresheje polyurethane mu gupfuka cyangwa mu gufunga, ubushuhe bushobora guteza ibibazo byinshi. Ushobora kubona uduheri, kwangirika kw'amazi, cyangwa ndetse no kwangirika kw'ibikoresho. Ibihumyo bishobora gukura iyo amazi yinjiriye mu bikoresho. Imbonerahamwe iri hepfo igaragaza ingaruka nyamukuru zo kuba amazi ashobora kubyangiza ku bikoresho bya polyurethane:

Ugomba gukemura ibi bibazo kugira ngo ibikoresho byawe bya polyurethane bigire icyizere kandi birambe igihe kirekire.

Imbogamizi muri sisitemu gakondo ya Isocyanate

Sisitemu gakondo za isocyanate zihura n'ibibazo byinshi iyo zihuye n'ubushuhe. Akenshi uhura n'ibibazo bidakenewe bigabanya ubuziranenge bwa polyurethane yawe. Dore bimwe mu bibazo bikunze kugaragara:

• Isocyanates zigira ingaruka vuba iyo zihuye n'ubushuhe, ibyo bikaba bishobora gutera ifuro no kwiyongera k'umuvuduko.
• Ubwo buryo butuma habaho urea na dioxyde de carbone, bigakuraho isocyanate ihari.
• Ibi bibazo bituma bigorana kugenzura imiterere ya nyuma y'ibicuruzwa byawe.

Ushobora gutsinda izi mbogamizi uhisemo ibisubizo bigezweho nka DDI (Dimeryl Diisocyanate) CAS NO. 68239-06-5. Ubu buryo bugufasha gukora polyurethane idafata amazi irwanya ubushuhe kandi ikamara igihe kirekire.

DDI (Dimeryl Diisocyanate) CAS NO. 68239-06-5: Umuti wa Polyurethanes zidakoresha amazi

Imiterere yihariye ya shimi OYA

Urashaka ko ibikoresho byawe bya polyurethane biramba kandi bigakomeza gukomera, ndetse no mu bihe by'ubushuhe. DDI (Dimeryl Diisocyanate) CAS NO. 68239-06-5 iragaragara cyane kubera imiterere yayo yihariye ya shimi. Iki kinyabutabire gifite umugongo muremure wa karuboni 36, utuma cyoroha kandi kigakomera. Ubukana buke butuma byoroha kuvanga no gufata. DDI kandi igaragaza uburozi buke, bityo ushobora kuyikoresha mu buryo bwizewe mu bikorwa byinshi.

Reka tugereranye DDI n'izindi isocyanati zisanzwe zikoreshwa mu gukora polyurethane. Imbonerahamwe iri hepfo igaragaza uburyo uburemere bwa molekile ya DDI, ingano ya NCO, n'uburozi bitandukanye n'ubundi buryo:

Urabona ko DDI (Dimeryl Diisocyanate) CAS NO. 68239-06-5 ifite uburemere bwinshi cyane bwa molekile kandi ifite uburozi buke kurusha izindi isocyanate. Ibi bivuze ko ubona ibicuruzwa bikize kandi bihamye.

Uburyo bwo Gusubiza Ugereranije n'izindi Isocyanate

Iyo ukoresheje DDI, ubona uburyo butandukanye bwo gukora ibintu ugereranije n'uburyo gakondo bwo gukora isocyanates. DDI ikorana na polyols kugira ngo ikore imigozi ikomeye ya urethane. Uruhererekane rurerure rwa karuboni muri DDI rufasha mu gukora umuyoboro woroshye. Uyu muyoboro urwanya kuvunika iyo uhuye n'amazi cyangwa stress.

Izindi isocyanati, nka TDI cyangwa MDI, zigira ingaruka vuba ku mazi. Ibi bishobora gutera ifuro no kudakora neza kwa polyurethane yawe. Imiterere ya DDI igabanya ingaruka zitari ngombwa iyo ikoreshejwe ubushuhe. Ugenzura neza inzira yo kuyitunganya. Igicuruzwa cyawe cya nyuma gikomeza kuba cyiza kandi gikomeye, nubwo haba hari ubushuhe mu gihe cyo kuyikoresha.

Inama: Gukoresha DDI bigufasha kwirinda ibibazo bikunze kugaragara nk'uduheri cyangwa imiturire mu irangi rya polyurethane yawe.

Ibisubizo by'Imikorere Mu Gihe cy'Indwara mu Menyo

Urashaka ko ibikoresho byawe bya polyurethane bikora neza, ndetse no mu bidukikije bitose cyangwa bitose. Polyurethane zishingiye kuri DDI zigaragaza umusaruro mwiza iyo zishyizwe mu mazi igihe kirekire. Zirwanya hydrolysis, bivuze ko amazi adasenya ibikoresho byoroshye. Ibi bituma ibicuruzwa byawe bimara igihe kirekire.

Dore incamake y'uburyo polyurethane zishingiye kuri DDI zikora iyo zihuye n'amazi:

Ushobora kwizera DDI (Dimeryl Diisocyanate) CAS NO. 68239-06-5 kugira ngo ibikoresho byawe bya polyurethane bigume bidakoresha amazi kandi byizewe. Ibi bituma biba amahitamo meza ku bijyanye no gusiga, gufunga, n'ibindi bikorwa aho ubushuhe ari ikibazo.

Kuramba no kuramba kurushaho

Urashaka ibikoresho bya polyurethane biramba. Iyo ukoresheje DDI (Dimeryl Diisocyanate) CAS NO. 68239-06-5, ubona irangi n'ibifunga birwanya amazi kandi bigakomeza gukomera. Polyurethanes zifite DDI zigabanya ubushyuhe bwinshi kandi zigatanga aside nkeya nyuma yo guhura n'ubushuhe bwinshi n'ubushyuhe bwinshi. Ibi bivuze ko ibicuruzwa byawe bigumana imiterere n'imikorere yabyo igihe kirekire. Ubona kandi umuhondo muke, bityo irangi ryawe risa neza nubwo ryaba ryarahuye n'imirasire ya UV.

Uburyo bwo gukoresha ibintu bitandukanye mu nganda

Ushobora gukoresha DDI mu nganda nyinshi. Ikora neza mu kurangiza imyenda, kole, elastomer, sealants, coatings, na wino. Usanga DDI mu bikorwa bya gisirikare ndetse na gisivili. Igufasha gukora imyenda idapfa amazi, coatings zikomeye ku mbaho ​​no mu byuma, na elastomer zoroshye. Ubona umusaruro wizewe waba ukora mu bwubatsi, imyenda, cyangwa imodoka.

Ibyiza by'Ikiguzi n'Imikorere

Urabona ko DDI idahumanya ibidukikije kandi irushaho gukundwa. Ibiciro bya DDI byaragabanutse, ariko diisocyanates zishingiye ku binyabuzima nka DDI zishobora kuba zihenze kurusha amahitamo asanzwe. Wishyura byinshi mbere y'igihe, ariko ubona inyungu mu mikorere. Polyurethanes zifite DDI zirwanya kubora no guhinduka umuhondo, bityo ukoresha make mu gusana no gusimbuza.

• DDI itanga uburyo bwo kurwanya amazi mu buryo bwiza.
• Urushaho kuramba no kudahindagurika kw'amabara.
• Ushyigikira ibidukikije mu bicuruzwa byawe.

Intambwe zo Guhuza OYA mu miterere ya Polyurethane

Ushobora kongeramo DDI mu miterere yawe ya polyurethane mu ntambwe nke zoroshye:

1. Hitamo polyol ikwiye gukoreshwa mu ikoreshwa ryawe.
2. Vanga DDI na polyol yawe mu gihe ugenzuye.
3. Hindura igipimo kugira ngo ugere ku bworoherane n'imbaraga wifuza.
4. Sukura uruvange ku bushyuhe busabwa.
5. Gerageza umusaruro wa nyuma kugira ngo urebe niba udashobora kunywa amazi kandi ko uramba.

Inama: Buri gihe kurikiza amabwiriza y'umutekano mu gihe ukoresha isocyanate.

Ushobora kwizera DDI (Dimeryl Diisocyanate) CAS NO. 68239-06-5 ku bicuruzwa bya polyurethane bidafata amazi kandi biramba. Inganda nyinshi ubu zihitamo iki gisubizo kubera umutekano wacyo, umusaruro uhoraho, ndetse n'agaciro k'isoko kagenda gakura.

• Agaciro k'isoko kazamutse kuva kuri miliyoni 120 z'amadolari y'Amerika kagera kuri miliyoni 450 z'amadolari y'Amerika mu myaka ibiri.
• Amabwiriza mpuzamahanga agena ikoreshwa ry’ibicuruzwa mu buryo bwizewe kandi bufite ishingiro.

Ibibazo Bikunze Kubazwa

Ni iki gituma DDI (Dimeryl Diisocyanate) byihariye kuri polyurethane zidafata amazi?

Ubona umugongo wa karuboni 36. Ibi biguha polyurethane yawe imbaraga zo kwirinda amazi, koroherana, kandi ikaba nta burozi bwinshi ifite.

Ese ushobora gukoresha OYA mu nganda zitandukanye?

• Ushobora gukoresha DDI mu myenda, irangi, kole, ibifunga, na wino.
• DDI ikorera ibikoresho bya gisirikare n'ibya gisivili.
