Ithini inkqubo yemveliso yeMethylceluplose?

Ithini indima ye-methyl sether i-ether yomgubo owomileyo?
A: Methyl HydroxyEtheetheethy I-Ether (MHC) kunye ne-Methyl Hydroxdpropyl ye-Ether (i-HPMC) zibizwa ngokuba yi-methyl seteli.

Kwintsimi yomgubo owomileyo, uMethyl Selerbase Ether sisixhobo esibalulekileyo sodaka, i-gesile ye-gele, i-ftty, i-felty, i-felpanel ye-celung kunye nempahla yengubo ye-glue. Kumgubo owomileyo owomileyo, i-methyl seluplose ether ikakhulu idlala indima yokugcinwa kwamanzi kunye nokutyibilika.

Ithini inkqubo yemveliso yeMethylceluplose?
Impendulo: Okokuqala, izixhobo zeselfowuni zityumkile, emva koko i-alkalid kwaye itsalwe phantsi kwesenzo se-caustic soda. Yongeza i-Olefin Oxide (njenge-Englone oxide okanye i-propylene oxide) kunye ne-methyl chloride ye-etheriya. Ekugqibeleni, ukuhlamba amanzi kunye nokucoca kwenziwa ukuba ekugqibeleni ufumane umgubo omhlophe. Lo mgubo, ngakumbi isisombululo se-AICOOO EZIQHELEKILEYO, Unepropathi yomzimba enomdla. The cellulose ether used in the construction industry is methyl hydroxyethyl cellulose ether or methyl hydroxypropyl cellulose (referred to as MHEC or MHPC, or a more simplified name MC). Le mveliso idlala indima ebaluleke kakhulu kwicandelo lomgubo owomileyo. Indima ebalulekileyo.

Luyintoni ukugcinwa kwamanzi kwe-methyl selete ye-ether (MC)?
Impendulo: Inqanaba lokugcina amanzi yenye yeempawu ezibalulekileyo zokulinganisa umgangatho we-methyl sether, ngakumbi kudaka olusekwe kwi-Gyppum. Ukugcinwa kwamanzi okuphuculweyo kunokuthintela ngempumelelo i-phenomenon yamandla elahleko kunye nokuqhekeka okubangelwa kukomile ngokugqithisileyo kunye nokungasebenzi kakuhle. Ukugcinwa kwamanzi okuhle kwe-methyl selether phantsi kweemeko zobushushu obuphezulu yenye yezona zinto zibalulekileyo zokwahlula intsebenzo ye-methyl seteli. Phantsi kweemeko eziqhelekileyo, ukugcinwa kwamanzi kwe-methyl eqhelekileyo ye-methyl yeselcelose kuyancipha ngokunyuka kobushushu. Xa iqondo lobushushu liphuma ukuya kwi-40 ° C, ukugcinwa kwamanzi kwi-methyl eqhelekileyo ye-methyl incitshisiwe kakhulu, kubaluleke kakhulu kwiindawo ezishushu nezilomileyo. Kwaye ukwakhiwa komzimba onqabileyo kwigumbi elinelanga ehlotyeni kuya kuba nefuthe elibi. Nangona kunjalo, ukwenza ukungagcinwa kwamanzi kwi-dosage ephezulu kuya kubangela i-viscofity ephezulu yezinto ezibonakalayo ngenxa yedosi ephezulu, eya kubangela ukungasebenzi.

Ukugcinwa kwamanzi kubaluleke kakhulu ukuphucula inkqubo yokuqinisa kweenkqubo zentshutshiso zemibhinqa. Phantsi kwesenzo se-Ilet Sether, umswakama ngokuthe ngcembe ukhutshelwe kwi-ofisi yesiseko okanye umoya ngaphezulu kwexesha elide, ngaloo ndlela eqinisekisa ukuba ixesha elininzi lokuphazamisa amanzi (i-gypsum) linexesha elide lokunxibelelana.
