Ojiji nke Hydroxypropyl Methylcellulose (HPMC)

Hydroxypropyl methylcellulosebụ ihe eji eme ihe na ụlọ ọrụ kemịkalụ ụlọ. Na mmepụta kwa ụbọchị, anyị nwere ike na-anụkarị aha ya. Mana ọtụtụ ndị amaghị ojiji ya. Taa, m ga-akọwa ojiji nke hydroxypropyl methylcellulose na gburugburu dị iche iche.

1. Ngwa ngwa owuwu, plasta ngwa agha

Dị ka onye na-ahụ maka mmiri na-ejigide mmiri na retarder maka ciment ciment, ọ nwere ike imeziwanye mgbapụta nke ngwa agha ahụ, kwalite mgbasawanye na ịgbatị oge ọrụ. Njide mmiri nke HPMC nwere ike igbochi slurry site na ịgbawa n'ihi ihicha ngwa ngwa mgbe ngwa ngwa, ma welie ike mgbe ọ gbasịrị.

2. Putty na-eguzogide mmiri

Na putty, cellulose ether na-arụ ọrụ nke njide mmiri, njikọta na mmanye, na-ezere mgbawa na akpịrị ịkpọ nkụ nke oke mmiri na-efunahụ, na n'otu oge ahụ na-eme ka adhesion nke putty dịkwuo elu, na-ebelata ihe ngosi nke sagging n'oge a na-ewu ụlọ, na ime ka ọ dịkwuo mma. na-ewu usoro smoother.

3. Plasta plasta

Na ngwaahịa gypsum, cellulose ether na-arụ ọrụ nke njide mmiri, ịgbara mmiri na mmanu mmanu, ma nwee mmetụta nkwụsịtụ n'otu oge ahụ, nke na-edozi nsogbu nke ike mbụ na-enweghị ike iru n'oge usoro ihe owuwu, ma nwee ike ịgbatị oge ọrụ.

4. Ihe ntanetị

A na-ejikarị ya eme ihe dị ka ihe na-esi ísì ụtọ, ọ nwere ike imeziwanye ike nkwụsị na ike ịkwa akwa, melite mkpuchi elu, welie adhesion na ike nkekọ.

5. Mgbochi mkpuchi nke mpụga maka mgbidi dị n'èzí

Cellulose ether na-arụkarị ọrụ nke njikọta na ike na-abawanye na ihe a. Ọ dị mfe ịkwanye ájá ájá, melite arụmọrụ ọrụ, ma nwee mmetụta nke mgbochi sag. Ịrụ ọrụ njigide mmiri dị elu nwere ike ịgbatị oge ọrụ nke ngwa agha ma melite nkwụsị nke nkwụsị na nkwụsị mgbawa, mma elu elu, ụba ike njikọ.

6, onye na-akpa ike, onye na-emekọ ihe ọnụ

Mgbakwunye nke cellulose ether na-enye ya ezigbo nchikota nke ihu, obere shrinkage na nguzogide abrasion dị elu, nke na-echebe ihe isi ala site na mmebi ngwaọrụ ma na-ezere mmetụta nke ịbanye n'ime ụlọ ahụ dum.

7. DC ihe dị larịị

Nkwekọrịta kwụsiri ike nke cellulose ether na-eme ka mmiri dị mma na ikike ịkwado onwe ya, ma na-achịkwa ọnụ ọgụgụ mmiri iji mee ka ike sie ike ngwa ngwa ma belata mgbawa na nkwụsị.

8. Agba latex

N'ime ụlọ ọrụ mkpuchi, a na-eji cellulose ethers mee ihe dị ka ndị na-eme ihe nkiri, ndị na-emepụta ihe, ndị emulsifiers na stabilizers, nke mere na fim ahụ nwere ezigbo nkwụsị nke abrasion, ọkwa, adhesion, na PH nke na-eme ka esemokwu dị elu dị mma , The miscibility na organic solvents dịkwa mma. , na nnukwu njigide mmiri na-eme ka ọ nwee ezigbo brushability na ọkwa osimiri.

Ekwenyere m na onye ọ bụla nwere nghọta ụfọdụ nke hydroxypropyl methylcellulose. Dị ka akụrụngwa dị mkpa na ụlọ ọrụ kemịkalụ ihe owuwu ụlọ, hydroxypropyl methylcellulose na-emetụta ogo ngwaahịa ala. Ya mere, mgbe ị na-ahọrọ hydroxypropyl methylcellulose, jide n'aka na ị ga-emeghe anya gị. Naanị akụrụngwa dị elu nwere ike ịmepụta ngwaahịa dị elu.
