Hydroxypropylmethylcellulose (HPMC) bụ polymer vasatail nke a na-ejikarị na ụlọ ọrụ ihe owuwu. Ọ bụ ihe na-adịghị egbu egbu, enweghị isi, pH na-akwụsi ike nke a na-emepụta site na iwebata hydroxypropyl na methyl n'ime cellulose eke. HPMC dị na ọkwa dị iche iche nwere viscosities dị iche iche, nha urughuru na ogo nke nnọchi. Ọ bụ polymer soluble mmiri nke nwere ike ịmepụta gels n'ogo dị elu ma ọ nweghị mmetụta ọ bụla na rheology nke mmiri na obere mkpokọta. Isiokwu a na-atụle ngwa nke HPMC dị iche iche ihe owuwu.
Ngwa nke HPMC na plasta na nsụgharị
Ịrụ ụlọ na-achọ ka mma n'elu ihe onwunwe nke mgbidi, ala na uko ụlọ. A na-agbakwunye HPMC na gypsum na plasta iji kwalite ọrụ ha na nrapado. HPMC na-eme ka ire ụtọ na nkwụsi ike nke plasta na ihe nkedo dị mma. Ọ na-eme ka mmiri na-ejide mmiri nke ngwakọta, na-enye ha ohere ka ha na-arapara nke ọma na mgbidi ma ọ bụ ala. HPMC na-enyekwa aka igbochi mbelata na mgbawa n'oge ọgwụgwọ na ihicha, na-abawanye ogologo oge nke mkpuchi.
Ngwa nke HPMC na nrapado tile
Ihe nrapado tile bụ akụkụ dị mkpa nke ọrụ owuwu ọgbara ọhụrụ. A na-eji HPMC eme ihe na nrapado taịlị iji meziwanye nrapado ha, njide mmiri na ịrụ ọrụ ihe owuwu. Ịtinye HPMC na usoro nrapado na-abawanye nke ukwuu oge oghere nke nrapado, na-enye ndị nrụnye oge ka ha mee mgbanwe tupu taịlị ahụ edozi. HPMC na-abawanye mgbanwe na ịdịte aka nke bondline, na-ebelata ihe ize ndụ nke delamination ma ọ bụ cracking.
Ngwa nke HPMC n'ime ogige ndị na-ebuli onwe ya
A na-eji ogige ndị na-edozi onwe ha na-eme ka ala dị larịị ma na-emepụta ihe dị mma, ọbụna maka ntinye nke ihe ndị dị n'ala. A na-agbakwunye HPMC na ogige ndị na-ebuli onwe ya ka ọ dịkwuo mma na-asọpụta na nhazi ọkwa ha. HPMC na-ebelata viscosity mbụ nke ngwakọta, na-eme ka ọ dị mfe itinye na imeziwanye ọkwa. HPMC na-abawanye njide mmiri nke ngwakọta, na-eme ka ike njikọ dị mma n'etiti ihe ala ala na mkpụrụ.
Ngwa nke HPMC na caulk
A na-eji grout emeju oghere n'etiti taịl nile, nkume eke ma ọ bụ ihe ala ndị ọzọ. A na-agbakwunye HPMC na ngwakọta njikọ iji meziwanye arụmọrụ ihe owuwu ya na ịdịte aka ya. HPMC na-abawanye viscosity nke ngwakọta, na-eme ka ọ dị mfe ịgbasa na ibelata shrinkage na cracking nke ihe ndochi n'oge ọgwụgwọ. HPMC na-emekwa ka adhesion nke ndochi ahụ dị na mkpụrụ, na-ebelata ohere nke oghere na mgbawa n'ọdịnihu.
HPMC na ngwaahịa gypsum
A na-eji ngwaahịa gypsum eme ihe, dị ka plasta, taịlị uko ụlọ na mbadamba ihe mkpuchi, na ụlọ ọrụ ihe owuwu. A na-eji HPMC eme ihe na ngwaahịa gypsum iji meziwanye arụmọrụ ha, ịtọ oge na ike. HPMC na-ebelata ihe mmiri chọrọ nke nhazi ahụ, na-enye ohere maka ọdịnaya siri ike dị elu, nke na-eme ka ike na ịdịte aka nke ngwaahịa emechara. HPMC na-emekwa ka adhesion dị n'etiti gypsum particles na mkpụrụ, na-eme ka njikọ dị mma.
na ngwụcha
Hydroxypropylmethylcellulose (HPMC) bụ polymer na-agbanwe agbanwe nke ejiri n'ụdị ihe owuwu dị iche iche. HPMC na-eme ka arụ ọrụ nke gypsum na plasta rụọ ọrụ, ihe ntanye tile, ogige na-edozi onwe ya, grouts na ngwaahịa gypsum. Iji HPMC n'ime ihe ndị a na-eme ka nhazi, nrapanye, njide mmiri na ịdịte aka. Ya mere, HPMC na-enyere aka ịmepụta ihe ụlọ siri ike, na-adịgide adịgide, na-adịte aka nke na-egbo mkpa dị elu nke ihe owuwu ọgbara ọhụrụ.
