Cov Ntsiab Cai Ntawm Cov Qauv Roj Hmab

1. Cov hauv paus ntsiab lus ntawm cov qauv siv roj hmab:

(1) Raws li daim ntawv thov cov khoom lag luam, xws li ntsuas kub, nruab nrab, kev ntxhov siab thiab lwm yam tshwj xeeb xav tau, thawj zaug xaiv hom roj hmab uas tsim nyog thiab tus neeg sawv cev sib xyaw kom ntseeg tau tias tau txais lub cev thiab cov khoom siv tau zoo tshaj plaws;

(2) Kev saib xyuas tshwj xeeb yuav tsum tau them rau cov qauv tsim Kev tsim nyog ntawm cov txheej txheem tsim khoom, xws li kev yooj yim ntawm kev sib xyaw cov roj hmab sib xyaw, kev yooj yim ntawm kev faib tawm ntawm cov khoom, cov kua dej ntawm cov khoom, qhov ua tiav ntawm cov khoom siv extruded, lwm.;.

(3) Ua ntej ua kom ntseeg tau qhov ua tau zoo ntawm cov khoom siv roj hmab thiab qhov ua tau ntawm kev ua haujlwm thev naus laus zis, sim txo cov nqi khoom, ua kom nrawm nrawm nrawm, thiab txhim kho kev ua haujlwm tau zoo;

(4) Kev siv cov khoom siv raw uas ua paug ib puag ncig yuav tsum zam kom ntau li ntau tau kom txo qis kev ua qias tuaj ib puag ncig thiab tiv thaiv kev noj qab haus huv ntawm cov tswv lag luam;

(5) Kev saib xyuas tshwj xeeb yuav tsum tau them rau kev sib cuam tshuam ntawm ntau tus neeg sawv cev sib xyaw. Qee tus neeg sawv cev sib xyaw tuaj yeem tsim cov txiaj ntsig sib xyaw. Piv txwv li, tus nrawm D tuaj yeem txhim kho kev tiv thaiv ntawm cov tshuaj tiv thaiv kab mob MB, thiab peroxides yog qhov yooj yim heev rau kev sib cuam tshuam nrog ib leeg ntawm qhov kub thiab txias. Cov tshuaj hydrogen-muaj cov tshuaj tau poob rau hauv cov tshuaj tiv thaiv, yog li thaum siv peroxide vulcanization, kev siv cov tshuaj muaj cov tshuaj ua kom muaj cov kuab lom, xws li amine antioxidants, stearic acid, thiab lwm yam, yuav tsum zam kom ntau li ntau tau.

Tag nrho txhua qhov, hauv kev tsim qauv, tshwj xeeb yuav tsum tau them rau qhov sib npaug zoo tshaj plaws ntawm lub cev thiab cov yam ntxwv ntawm cov roj hmab sib xyaw, kev tsim khoom thiab ua tiav kev ua tiav thiab cov khoom siv. Tib lub sijhawm, yuav tsum tau them nyiaj tshwj xeeb rau yam xws li kev tiv thaiv ib puag ncig thiab kev nyab xeeb.

Kev faib cov mis roj hmab

Muaj ntau txhiab hom khoom siv roj hmab. Nws tsis yog kev tshawb fawb los cais cov mis raws li cov khoom lag luam, thiab nws yog qhov tsim nyog ntau dua los cais raws li qhov ua tau zoo. Piv txwv li, thaum ntsuas qhov hnav tsis kam siv los ua tus qauv ntsuas thawj, nws yog thawj qhov hnav tsis kam rau yam khoom twg. Roj tsis kam, kua qaub thiab alkali tsis kam.

Thiab ntxiv rau thiab ntxiv rau. Nws kuj tseem tsis tau lees paub cais cov roj hmab nyoos los ntawm nws cov khoom tseem ceeb. Hauv cov ntaub ntawv uas twb muaj lawm, nrog kev nce qib ntawm kev tshawb fawb, feem ntau nws yog siv cov khoom sib xyaw ntawm ntau cov ntaub ntawv tshiab thiab txheej txheem txheej txheem txhawm rau kom tau txais tus nqi qis, ua tau zoo tshaj ntawm cov qauv. Qhov no tseem ceeb heev hauv kev sib tw khoom lag luam niaj hnub no. Yog li ntawd, cov roj hmab mis muaj lub zog txiav txim siab muaj nuj nqis ntawm tus nqi tsim khoom ntawm cov khoom lag luam roj hmab thiab cov txiaj ntsig kev lag luam.
