Roj hmab cov ntaub ntawv tshuaj ntsuam poov tshuaj hydroxide (koh) hluavtaws roj hmab ntau lawm

Cov roj hmab cov khoom ua si ib qho tseem ceeb hauv kev lag luam, los ntawm kev siv tsheb mus rau kev kho mob. Ib qho tseem ceeb tseem ceeb hauv kev tsim hluav taws xob ntau lawm yog cov poov tshuaj hydroxide (koh). Koh yog cov tshuaj tseem ceeb hauv cov txheej txheem roj hmab tsim, raws li nws ua raws li kev ua yeeb yam hauv cov roj hmab hluav taws xob hluavtaws.

Cov roj hmab ntau lawm yuav ua rau cov polymerization ntawm ntau cov monomers los tsim cov saw ntev ntawm cov roj hmab molecules. Koh yog siv los pib thiab ua kom ceev cov txheej txheem polymerization, ua rau muaj kev tsim cov khoom siv muaj zog thiab hloov roj hmab. Ib qho ntxiv, Koh pab tswj cov molecular hnyav thiab cov qauv ntawm cov roj hmab hluavtaws, kom nws ua tau raws li cov ntaub ntawv tshwj xeeb.

Hauv cov roj av kev lag luam, cov roj hmab hluavtaws tau dhau los ua nws cov txiaj ntsig durabiles, tiv taus kom sov thiab tshuaj lom neeg. Khoom siv roj hmab hluavtaws roj yog siv ntau yam khoom lag luam, suav nrog cov log tsheb, hoses, ntsaws ruaj ruaj, gastets, thiab cov siv tawv. Kev siv ntawm Koh hauv kev tsim cov roj hmab ntau lawm pab txhim kho kom zoo dua qub thiab ua haujlwm ntawm cov ntaub ntawv no.

Ib qho ntawm qhov tseem ceeb ntawm cov hluavtaws roj hmab ntau lawm siv koch yog lub peev xwm los kho cov khoom ntawm cov roj hmab kom tau raws li cov cai. Los kho cov nyiaj ntawm koh thiab lwm yam kev ntxiv nrog cov txheej txheem polymerization, cov chaw tsim khoom tuaj yeem tsim cov yam ntxwv ntawm cov roj hmab hluav taws xob kom haum cov ntawv thov sib txawv. Qhov kev hloov pauv no tso cai rau kev tsim cov roj hmab cov ntaub ntawv nrog ntau yam ntawm cov yam ntxwv, xws li hardness, elasticity, thiab tshuaj lom neeg kuj.

Tsis tas li ntawd, kev siv ntawm koh hauv hluavtaws roj hmab ntau lawm yuav pab txhim kho cov txheej txheem kev tsim khoom. Koh ua raws li catalyst, txo lub sijhawm thiab lub zog yuav tsum rau polymerization, thiab nce cov txiaj ntsig ntawm cov khoom siv roj hmab zoo. Qhov no tsis tsuas yog cov txiaj ntsig cov txiaj ntsig los ntawm streamlining cov txheej txheem ntau lawm tab sis kuj txo cov nqi thiab txhim kho cov khoom lag luam thiab txhim kho cov khoom ua haujlwm.

Hauv kev xaus, tshuaj pleev iav hydroundcide (koh) ua lub luag haujlwm tseem ceeb hauv cov khoom siv roj hmab ntau lawm. Los ntawm kev ua haujlwm ua ib qho kev ua yeeb yam hauv cov txheej txheem polymerization, Koh pab tsim cov khoom lag luam siab ntawm cov khoom siv rau ntau yam kev siv. Kev siv ntawm Koh hauv cov roj hmab hluavtaws hluavtaws ntau lawm ua kom tau zoo, raug nqi, ua rau nws ua haujlwm tseem ceeb hauv cov roj hmab tsim kev lag luam.

Pob:25 kg nruab nrab hnab, jumble hnab, lossis ibc nruas.

Chaw Cia:

Qhuav ib puag ncig: Khaws nws rau hauv qhov txias, qhuav, zoo - pa thaj chaw kom tiv thaiv kev nqus dej noo.

Deb ntawm cov kua qaub: Koh yuav tsum tau muab cia kom deb ntawm cov kua qaub, raws li nws tuaj yeem hnov ​​cov kev sib raug zoo nrog cov tshuaj acidic.

Qho so: Khaws ntawm chav tsev kub thiab zam kev ua rau nws kom huab cua sov heev, uas yuav ua rau muaj feem muaj feem ntawm cov kev tawm tsam.
