1. The CommonalityAnd Dkev xavBib nrabPolyurethane uaAnd EpoxyResin:

CovKev sib koom ua ke:

1)Polyurethane thiab epoxy resin yog ob qho tib si, thiab cov khoom siv thiab kev ua haujlwm yog qhov zoo ib yam;

2)Ob leeg muaj zog tensile zoo, tsis muaj cracking, tsis ntog thiab lwm yam khoom;

3)Ob leeg muaj cov khoom ntawm corrosion tsis kam rau cov kua qaub, alkali, ntsev thiab ntau yam roj;

4)Ob leeg muaj cov khoom ntawmtsis muaj plua plav, waterproof, nto hnav tsis kam, hnyav siab ua haujlwm, cuam tshuam tsis kam thiab lwm yam;

The Difference:

1)Polyurethane (PU)yog polyphenylene diisocyanate thiab polyether polyol.Nws yog cross-linked thiab     kho nyob rau hauv lub xub ntiag ntawm catalyst triethylene diamine los ua siab polymer.Piv nrog epoxy resin, nws yog tshuaj lom ntau dua.

Polyurethane muaj cov yam ntxwv ntawm adhesion zoo, rwb thaiv tsev thiab huab cua tsis kam.Lub hardness tuaj yeem hloov pauv los ntawm kev kho cov ntsiab lus ntawm diisocyanate thiab polyether polyol, thiab nws tuaj yeem siv rau hauvntim ntawm ntau yam khoom siv hluav taws xob thiab hluav taws xob.

2)Epoxy cob feem ntau yog tsim los ntawm bisphenol A epoxy resin, curing agent (amine los yog acid anhydride), auxiliary agent, muab tub lim, thiab lwm yam. Nws muaj lub sij hawm ntev curing ntawm chav tsev kub thiab tuaj yeem kho tau los ntawm cua sov.Tom qab kho, nws muaj kev sib txuas siab zog thiab hardness.Feem ntau, nws yog qhov loj thiab tuaj yeem ua pob tshab rau encapsulate hluav taws xob modules thiab diodes.

Polyurethane muaj huab cua zoo dua, tsis tawg ntawm qhov kub thiab txias, thiab yog me ntsis kim dua.

2.Kev siv ntawm polyurethane thiab epoxy resin:

1) Polyurethane cob:

Polyurethane resin yog cov khoom siv polymer nrog lub zog siab, tsim kua muag, hnav tsis kam thiab lwm yam ntxwv;

Siv raws lirollers, conveyor siv, hoses, auto qhov chaw, khau khau, hluavtaws tawv, cov kab mob thiab kab mob thiabkev kho mob cov kabmob, lwm.;

Rau kev tsim cov khoom yas, hnav-resistant hluavtaws roj hmab cov khoom, hluavtaws fibers, rigid thiab saj zawg zog ua npuas ncauj cov khoom,nplaum thiab coatings, thiab lwm yam;

Nws yog siv rau kev ua tiav ntawm ntau yam khoom siv ntoo, cov khoom siv tshuaj, cov khoom siv sib txuas lus thiab cov cuab yeej siv thiab ntau yam kev thauj mus los.

2)Epoxy resin: kuj tuaj yeem siv rau hauv cov txheej txheem, cov nplaum, cov ntaub ntawv sib xyaw, thiab lwm yam.

Epoxy resin txheej yog ib hom muaj zog, hnav-tiv taus thiab zoo nkauj hauv pem teb, uas muaj qhov zoo ntawm seamless, khoom zoo nkauj, zoo tshuaj tiv thaiv, tiv thaiv corrosion, plua plav pov thawj, yooj yim txij nkawm thiab tsis tshua muaj nqi tu.

Ntau yam txheej txheem tuaj yeem tsim raws li cov neeg siv khoom xav tau, xws li txheej txheej nyias, 1-5mm tuab nws tus kheej-leveling pem teb, anti-skid thiab hnav-resistant pem teb, mortar pem teb, anti-static, anti-corrosion pem teb, thiab lwm yam.

Cov khoom tsim nyog rau ntau qhov chaw, xws li kev cob qhia, chav computer, warehouses, laboratory, wards, operating room, workshops, etc.

3. Cov yav dhau los topcoat yog tsim rau siv sab nraum zoov, thaum lub tom kawg yog haum rau siv sab hauv tsev;

Qhov loj tshaj tsis muaj zog los yog qhov tsis zoo ntawm qhov kawg yog tias nws ntshai tsam muaj zog ultraviolet hluav taws xob, thiab nws yuav tig daj nyob rau hauv muaj zog ultraviolet hluav taws xob, uas yog, ploj, tab sis nws yuav tsis decompose thiab yuav tsis cuam tshuam rau kev siv;

Txawm li cas los xij, qhov qub tau zoo dua qub hauv huab cua tsis zoo dua li yav tas los, tshwj xeeb tshaj yog lub sijhawm yellowing ntawm lub qub yog ntev dua li ntawm yav tas los, yog li cov qub feem ntau siv rau kev tsim kho sab nraum zoov.
