Cov Kab Mob Siv Tshuaj

Cov neeg sawv cev tawv yog hais txog cov tshuaj uas tuaj yeem ua kom tau qhov yooj yim ntawm cov nplaum nplaum nplaum. Qee qhov thermosetting cob cov nplaum, xws li epoxy cob qhia, thaum muaj kev nthuav dav polyester, thiab muaj ntau dua kev tawg, nkees tsis kam, tuaj yeem tsis siv raws li cov txheej txheem kev sib koom tes. Yog li ntawd, nws yog qhov tsim nyog yuav txo tus brittleness, nce kev nruj thiab txhim kho kev sib tw lub zog. Cov khoom siv uas tuaj yeem txo cov brittleness thiab nce kev txo hwj chim yam tsis cuam tshuam rau lwm cov khoom tseem ceeb ntawm cov nplaum yog cov neeg sawv cev nruj. Nws tuaj yeem muab faib ua cov roj hmab nruj thiab thermoplastic elastomer puas xyov tus neeg sawv cev

Khoom Taw Qhia thiab Nta

(1) Cov roj hmab topening tus neeg sawv cev muaj ntau yam feem ntau yog suav nrog roj hmab polysulretades, antrile propeles roj hmab thiab styrene butadiene roj hmab, thiab lwm yam.
(2) thermoplastic elastomer thermoplastic elastomer yog ib hom hluavtaws uas pom cov roj hmab elasticity ntawm chav tsev kub thiab tuaj yeem muab closicity ntawm chav tsev kub thiab tuaj yeem muab cov yas hloov kho kub. Yog li no, hom ntawm cov yam ntxwv muaj cov yam ntxwv ntawm ob lub roj hmab thiab thermopastic, nws tuaj yeem siv ua cov khoom siv nruj ntawm cov khoom siv sib xyaw, thiab tuaj yeem siv ua cov khoom sib xyaw ntawm cov khoom sib xyaw. Cov ntaub ntawv zoo no tsuas yog suav nrog polyurethane, styrethane, polyolefin, polyoster, nyob rau lwm cov neeg tus neeg sawv cev ntawm cov khoom siv sib xyaw thiab cov polyolefin.
(3) Cov neeg sawv cev nruj dua lwm cov neeg sawv cev nruj dua rau cov neeg muaj kev sib xyaw muaj cov xim tsis muaj zog thiab cov neeg sawv cev qis dua qub, xws li cov phthalate estres. Tus neeg sawv cev tawv ua haujlwm tsis ua haujlwm yuav tseem hu ua yas, uas tsis koom nrog kev kho cov tshuaj tiv thaiv ntawm lub resin.

kev siv

Cov neeg sawv cev nruj yog qhov haum rau cov nplaum, roj hmab, txheej thiab lwm yam khoom. Nws yog ib hom neeg sawv cev uas tuaj yeem txo cov brittleness ntawm cov khoom siv sib xyaw thiab txhim kho cov kev cuam tshuam ntawm cov khoom siv sib xyaw. Nws tuaj yeem faib ua cov neeg saib xyuas nruj thiab cov neeg sawv cev ua kom nruj. Cov neeg sawv cev ua kom muaj zog kho nws cov molecular muaj cov txheej txheem nquag uas muaj peev xwm ua tau nrog cov qauv sib xyaw, thiab yog li txhim kho qhov cuam tshuam ntawm cov khoom siv sib xyaw. Ua haujlwm rau lub zog nruj yog ib hom neeg sawv cev tawv uas yog soluble nrog matrix cob qhia tab sis tsis koom nrog hauv kev siv tshuaj lom neeg

Pob Thiab Thauj

B. Cov khoom lag luam no tuaj yeem siv ,, 25kg, baerls.
C. Cov khw ntim khoom txias rau hauv qhov chaw txias, qhuav thiab muaj qhov cua nyob sab hauv tsev. Cov ntim yuav tsum kaw kom nruj nreem tom qab siv ua ntej siv.
D. Cov khoom no yuav tsum tau muab kaw zoo thaum caij tsheb thauj mus los kom tiv thaiv noo noo, muaj zog alkali, nag, nag los ntawm kev sib xyaw.
