Qhov txawv ntawm Polyurethane thiab Epoxy Resin yog dab tsi?

1. Kev Sib Tham Thiab Qhov Sib Txawv Ntawm Polyurethane Thiab Epoxy Resin:

Lub Koom Txoos:

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

2) Ob leeg muaj zog tensile zoo, tsis muaj cracking, tsis poob 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 ntawm plua plav, tsis muaj dej, tsis muaj dej, hnav tsis kam, hnyav ua haujlwm, cuam tshuam thiab lwm yam;

Qhov txawv:

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 rau 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 hauv ntim ntawm ntau yam khoom siv hluav taws xob thiab hluav taws xob.

2) Epoxy resin 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 cov 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 parts,khau khau, hluavtaws tawv, xov hlau thiab cables thiab cov khoom siv kho mob, thiab lwm yam .;

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

Nws yog siv rau kev ua tiav ntawm ntau yam ntoo, cov cuab yeej 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 tus nqi qis.

Ntau lub tswv yim 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 qhov tsis muaj zog lossis 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 mus, 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.
