Ntau txoj kev coj ua roj hmab

1. Tsis kam mus rau qhov hnyav nruab nrab nce

Cov khoom tiav tiav tuaj yeem raug kuaj, tsau rau hauv ib lossis ob peb cov ntaub ntawv xaiv, thiab lub sijhawm thiab sijhawm, thiab lub sijhawm hloov pauv raws li tus nqi hnyav thiab hloov tawv.

Piv txwv li, raus hauv 100 cov roj degree rau 24 teev, eco, sr, epdness dua li ob npaug ntawm qhov hnyav, thiab lub ntim nthuav dav yog pom tseeb.

2. Cov huab cua kub kub

Coj cov qauv los ntawm cov khoom tiav, muab lawv tso rau hauv lub thawv laus rau ib hnub, thiab saib qhov tshwm sim tom qab kev laus. Davual kev laus yuav muaj maj mam nce ntxiv. Piv txwv li, CR, thiab SBR yuav muaj nkig ntawm 150 degrees, thaum NBR EPDM tseem ywj. Thaum qhov kub nce mus rau 180 degrees, tus zoo tib yam dab tsi dog dig yuav nkig; Thiab HNBR yuav muaj ntsis ntawm 230 degrees, thiab roj hmab fluorine roj hmab thiab silicone tseem muaj elicastity zoo.

3. Combusionions

Nqa cov qauv me me thiab hlawv nws hauv huab cua. Saib qhov tshwm sim.

Feem ntau hais lus, fluorine roj hmab, CR, CSM muaj kev ywj pheej los ntawm hluav taws, thiab txawm tias cov nplaim taws yog hlawv, nws yog qhov me dua li cov NRERIVAL NROOG dav thiab EPDM. Tau kawg, yog tias peb saib kom zoo, lub xeev ntawm kev sib txuas, xim, thiab ntxhiab kuj muab peb cov ntaub ntawv ntau. Piv txwv li, thaum nbr / pvc yog sib xyaw nrog kua nplaum, thaum muaj hluav taws kub, qhov hluav taws kub txaws thiab zoo li dej. Nws yuav tsum raug sau tseg tias qee zaum cov nplaim taws retardant tab sis halogen-dawb kua nplaum yuav tseem yuav tsum tau inferred ntxiv los ntawm lwm txoj kev.

4. Ntsuas cov kev sib nqus

Siv cov hluav taws xob nplai lossis ntsuas qhov sib npaug, raug rau 0.01 gram, ntxiv rau khob dej thiab plaub hau.

Feem ntau hais lus, cov tshuaj lom neeg fluorine tau muaj lub zog loj tshaj plaws, saum toj no 1.8, thiab feem ntau ntawm CR Eco cov khoom muaj cov feem ntau tshaj li saum toj no 1.3. Cov teeb meem no tuaj yeem txiav txim siab.

5. Cov Qauv Kub Kub

Nqa cov qauv los ntawm cov khoom tiav thiab siv dej khov thiab dej khov kom qhuav los tsim ib qho chaw uas haum cryogenic ib puag ncig. Soak tus qauv hauv qhov chaw kub tsawg rau 2-5 feeb, hnov ​​qhov muag muag thiab tawv tawv ntawm qhov ntsuas kub. Piv txwv li, ntawm -40 degrees, tib lub siab kub thiab roj kuj silica gel thiab cov roj hmab roj hmab silicine yog muab piv, thiab cov roj fluora gel yog softer.
