Hydroxypropyl methylcellulose (HPMC) n'ime ngwa agha mmiri-agwakọta

Ọrụ nkeHPMC na ngwa agha agwakọtara mmiri

Ngwakọta mmiri na-agwakọta mmiri bụ ciment, nchịkọta dị mma, ihe mgbakwunye, mmiri na ihe dị iche iche kpebisiri ike dabere na arụmọrụ. Dị ka akụkụ ụfọdụ si dị, mgbe a tụrụ ya ma gwakọta ya na ebe a na-agwakọta ya, a na-ebuga ya na ebe a na-eji igwekota igwe, ma tinye ya n'ime ihe pụrụ iche A na-echekwa mmiri mmiri n'ime akpa ahụ ma jiri ya mee ihe n'ime oge a kapịrị ọnụ.

A na-eji Hydroxypropyl methylcellulose mee ihe dị ka ihe nchebe maka cement slurry yana dị ka onye na-azụ azụ iji mee ka slurry na-agbapụta. Hydroxypropyl-Methyl Cellulose HPMC Cellulose's ike moisturize dị ka viscous ngwọta na-abawanye irè nke dab na ịgbatị oge na-arụ ọrụ. Nke a na-enye ohere ka sesame ghara ịgbawa ngwa ngwa mgbe mmanye mmanye na-abawanye ike mgbe akpọnwụchara. . Hydrochloric acid bụ ọrụ dị mkpa nke HPMC iji hydrolyze cellulose, ọ bụkwa onye na-emepụta ọtụtụ pulps na China. Ihe na-emetụta slurry mmiri gụnyere ego mgbakwunye HPMC, viscosity HPMC, ịdị mma urughuru na ọnọdụ okpomọkụ.

Ọrụ dị mkpa nke HPMC na mmiri mix na-egosipụtakarị na akụkụ atọ: otu bụ ikike njigide mmiri dị mma, nke ọzọ bụ mmetụta na nkwụsi ike na nrụrụ anụ ahụ nke mmiri mix, na nke ọzọ bụ mmekọrịta na ciment. Ọnụ ọgụgụ nke cellulose ether na-adabere n'inweta mmiri site na mkpụrụ, ihe mejupụtara nke ájá, ọkpụrụkpụ nke oyi akwa, mkpa mmiri dị na ngwọta, na oge nkwụsị nke ihe.

Ihe njide mmiri na-emetụta cellulose hydrolyzed gụnyere viscosity pulp, ego mgbakwunye, ịdị mma na okpomọkụ. Ka nnukwu cellulose ether, ka mma mmiri na-eguzogide. Viscosity bụ ihe dị mkpa arụmọrụ oke nke HPMC. Maka otu ngwaahịa ahụ, nsonaazụ viscosity a tụrụ site na ụzọ dị iche iche dịgasị iche iche dị iche iche, ụfọdụ na-erutekwa ọganihu geometric. Ya mere, iji tụnyere viscosities, ọ dị mkpa ka eme n'etiti otu ụzọ ule, gụnyere okpomọkụ, spindle, wdg.

N'ikwu okwu n'ozuzu, ka viscosity dị elu, ka mma na-arụ ọrụ mgbochi mmiri. Ma ka ukwuu na-abawanye na viscosity, HPMC, elu nke molekụla arọ, ala solubility Njirimara, ihe ngwọta dị ike, na ihe onwunwe na-adịghị emetụta. Nke dị elu na viscosity, mma ndị ndim mmetụta na ngwọta, ma ọ bụghị kpọmkwem nhata ka ruru. Nke dị elu nke viscosity, mmiri na-ekpo ọkụ na ihe ngwọta, mgbe a na-ewu ụlọ, na-egosi nguzogide dị elu na ọnụnọ nke eriri na-egbuke egbuke na ihe. Mana ịgbakwụnye ike nhazi na ngwa agha mmiri n'onwe ya agaghị enyere aka. Mgbe e wuru ụlọ abụọ ahụ, a chọpụtara na ọrụ mgbochi anwụnta adịghị. N'ụzọ dị iche, ụfọdụ obere viscosity post-gbanwetụrụ methacrylic acid, ebe cellulose na-eme ka ngwọta mmiri na ike nhazi, nwere ihe ndị magburu onwe ya.
