Cov chaw thov tseem ceeb thiab cov haujlwm ntawm cov neeg hla kev hla

Tso lus

Taiic (Kev ua tsis tau zoo isocyanurate) yog ib tug multifunctional olefin monomer muaj cov ntxhiab heterocycles. Peb pawg allyl hauv nws cov qauv molecular ua rau nws nquag mus rau polymerization raws li peroxide kev pib, sib sau cov qauv network.

 

Cov yam ntxwv no ua rau nws siv dav rau kev ua haujlwm ntawm cov khoom siv polymer, txhim kho cov roj hmab, thiab hluav taws xob tshwj xeeb, thiab rwb thaiv tsev hluav taws xob los ntawm kev sib txuas hluav taws xob; Ntau kev hloov kho kev ua haujlwm: tuaj yeem siv ua cov sulphurizing tus neeg sawv cev, yas, lossis nruab nrab kom tau raws li cov kev xav tau sib txawv. ‌

 

Daim ntawv thov lub ntsiab thiab cov luag haujlwm tseem ceeb


1, crosslinking hloov kho ntawm thermoplastic ntaub ntawv
Siv tau cov ntaub ntawv: polyethylene, polyvinyl chloride eva, polystyrene, thiab lwm yam.
Cov nyhuv: qhov sib ntxiv ntawm cov cua sov hla yog 1-3% (sib txuas nrog cov hluav taws xob tiv thaiv tshav kub yog 0.2-1%), thiab ib qib retardancy, thiab lub tshuab kho tshuab muaj zog; ‌
Ntau cov phooj ywg ib puag ncig (ntxhiab tsw) thiab ua tau zoo dua li ib txwm muaj peroxide crosslinking tshuab. ‌

 

2, pab vulcanization ntawm cov roj hmab tshwj xeeb
Siv cov roj hmab muaj cov roj hmab: Ethylene Propylene cov roj hmab, fluororubber, colorinated polyethylene (CPE), thiab lwm yam)
Mechanism ntawm kev nqis tes ua: thaum ua ke nrog DCP (0.5-4%), nws shequens lub sij hawm vulcanization, txhim kho cov kev coj tsis kam, corrosion tsis kam, thiab cov kuab tiv thaiv. Txhim kho cov kub tiv thaiv ntawm CPE vulcanized roj hmab los ntawm kev nce cov ntoo khaub lig hla kev ntom ntom. ‌

 

3, crosslinking thiab hloov kho ntawm resin cov tshuab
Ion sib pauv resin: hloov cov kev siv divinylenzene, txo cov purining tsis kam, acid thiab pore loj uniformity; ‌
Unsaturated polyester: ntxiv rau nce cov cua sov tsis kam ntawm cov khoom siv fiberglass cov khoom rau 180-200 degree; ‌
Epoxy Resin / Dap Resin: txhim kho adhesion, seem ruaj khov, thiab kev siv tshuab lub zog, haum rau cov khoom ntim ntim hauv hluav taws xob. ‌

 

4, lwm lub hom phiaj tshwj xeeb
Homopoler daim ntawv thov: Taic tus kheej polymerizes kom tsim pob tshab yas, uas yog siv rau cov iav kev nyab xeeb ntau txheej txheem lossis kev sib txuas lus sib luag;
Kev tiv thaiv hlau: Npaj ua cov roj ci ci muab cov hluav taws xob tsis kam thiab tiv thaiv, haum rau microelectronic rwb thaiv tsev cov ntaub ntawv; ‌
Nruab nrab synthesis: siv rau UV kho cov txheej txheej, nplaim taws retardants (xws li TBC), thiab lwm yam.
