Uru na Ngwa nke Methyl Hydroxyethyl Cellulose (MHEC)

1. Nchịkọta

Methyl Hydroxyethyl Cellulose (MHEC), nke a makwaara dị ka Hydroxyethyl Methyl Cellulose, bụ ether cellulose nonionic. A na-enweta usoro ihe omimi ya site na iwebata otu methyl na hydroxyethyl na otu hydroxyl dị na molekul cellulose. N'ihi ihe pụrụ iche nke anụ ahụ na kemịkal ya, MHEC ejirila ọtụtụ ebe dịka ihe owuwu, mkpuchi na ihe ịchọ mma.

2. Uru nke MHEC

Ọmarịcha arụmọrụ thickening
MHEC nwere ikike ịgbatị nke ọma na enwere ike ịgbaze ya na mmiri na ihe mgbaze organic pola iji mepụta ngwọta doro anya ma kwụsie ike. Nke a na ndim ike na-eme ka MHEC dị irè na formulations na-achọ ukpụhọde nke rheological Njirimara.

Ezigbo njide mmiri
MHEC nwere nnukwu njigide mmiri ma nwee ike belata ikuku mmiri na ihe eji arụ ọrụ nke ọma. Nke a dị mkpa iji melite nhazi nke ihe onwunwe na arụmọrụ nke ngwaahịa ikpeazụ (dị ka ike na ike).

Njirimara mmepụta ihe nkiri mara mma
MHEC na-enwe ike ịmepụta ihe nkiri siri ike, nke na-egbuke egbuke mgbe ihicha, nke dị mkpa karịsịa na mkpuchi na ihe mkpuchi, ma nwee ike imeziwanye ihe na-adịgide adịgide nke mkpuchi ahụ.

Njirimara kemịkalụ kwụsiri ike
Dị ka ether cellulose na-abụghị ionic, MHEC nwere nkwụsi ike dị mma na acids, alkalis na salts, adịghị emetụta ihe ndị metụtara gburugburu ebe obibi na-adịghị mfe, ma nwee ike ịnọgide na-eguzosi ike n'elu pH buru ibu.

Obere iwe na nchekwa
MHEC abụghị ihe na-egbu egbu na ihe na-emebi emebi, na-adịghị akpasu ahụ mmadụ iwe, a na-ejikwa ya na ngwaahịa nlekọta onwe onye na ubi nri, na-ezute ụkpụrụ nchekwa dị iche iche nke mba ụwa.

3. Isi ngwa nke MHEC

Ihe owuwu ụlọ
A na-eji MHEC eme ihe n'ọtụtụ ebe dị ka ihe mgbakwunye maka ciment dabeere na gypsum na-adabere na ihe ndị e ji ewu ụlọ, dị ka putty ntụ ntụ, ngwa agha, adhesives, wdg Ya ndim na mmiri njigide Njirimara nwere ike imeziwanye ewu na oge ọrụ, gbochie cracking, na welie ihe. adhesion na mkpakọ ike nke ikpeazụ ngwaahịa. Dịka ọmụmaatụ, na nrapado taịlị, MHEC nwere ike ịnye ọmarịcha slip na oge oghe, ma melite mmetụta nrapado nke taịlị.

Ụlọ ọrụ agba
Na agba, a na-eji MHEC eme ihe dị ka ihe na-eme ka ọkpụkpụ na ihe na-eme ka ọ dịkwuo mma iji meziwanye mmiri na nkwụsi ike nke agba, na-eme ka ihe nkiri na-emepụta ihe na-eme ka ihe nkiri na-eme ka ọ dịkwuo mma. Enwere ike iji MHEC mee ihe n'ime ime na mgbidi mgbidi, ihe ndị na-emepụta mmiri, wdg iji hụ na a na-ekesa agba ahụ nke ọma n'oge a na-ewu ụlọ ma na-eme ka ịdịte aka na ihe mgbochi nke mkpuchi.

Ngwaahịa nlekọta onwe onye
A na-eji MHEC eme ihe na ngwaahịa nlekọta onwe onye dị ka ncha ntutu, ntụ oyi, ude mmiri, wdg dị ka onye na-agba agba, onye na-akwụsịtụ na ihe nkiri mbụ. Ọ nwere ike melite udidi nke ngwaahịa ahụ, mee ka ọ dị nro, ma kwalite nrụpụta nke ngwaahịa nlekọta anụ ahụ na ngwaahịa nlekọta ntutu isi.

Ọgwụ na nri
Na ọgwụ ubi, MHEC nwere ike ji mee ihe maka ịchịkwa ntọhapụ ọgwụ mkpuchi, ndim nkwusioru, wdg N'ime nri, MHEC nwere ike iji dị ka a thickener na stabilizer iji melite uto na nkwụsi ike nke ngwaahịa, na dị ka abụba dochie iji belata calories. .

Adhesives na Sealants
Enwere ike iji MHEC mee ihe dị ka onye na-agba ume na stabilizer na adhesives na sealants iji nye ezigbo viscosity mbụ na nkwụsị mmiri. Enwere ike iji ya na ngwa ndị dị ka ntinye akwụkwọ, akwa akwa na mkpuchi ụlọ iji hụ na arụmọrụ dị elu na nkwụsi ike nke nrapado.

Ịkụpụta mmanụ
A na-eji MHEC eme ihe dị ka ihe mgbakwunye iji chịkwaa rheology nke mmiri na-egwupụta mmanụ, nke nwere ike ime ka mmiri na-egwupụta ihe nwee ike ibu mkpụkọ, chịkwaa mmiri na-efunahụ, ma melite ịrụ ọrụ nke ọma.

4. Usoro mmepe na atụmanya ahịa
Site na mmepe na-aga n'ihu nke ụlọ ọrụ ihe owuwu, ngwaahịa nlekọta onwe onye, ​​​​na ụlọ ọrụ mkpuchi, ọchịchọ maka MHEC na-aga n'ihu na-eto eto. N'ọdịnihu, atụmanya ahịa nke MHEC na-ekwe nkwa, karịsịa n'ihe gbasara ịba ụba nke ihe ndị na-acha akwụkwọ ndụ akwụkwọ ndụ na gburugburu ebe obibi. Àgwà ọma ya na-emebi emebi na nke dị nchebe na nke na-adịghị egbu egbu ga-eme ka e jiri ya mee ihe n'ubi ndị ọzọ na-apụta.

Ọganihu teknụzụ akwalitela njikarịcha usoro mmepụta MHEC, belata ọnụ ahịa mmepụta, yana mma ngwaahịa na arụmọrụ. Ntuziaka nyocha n'ọdịnihu nwere ike ilekwasị anya n'ịkwalite ọrụ nke MHEC, dị ka site n'iwebata otu ọrụ dị iche iche ma ọ bụ ịmepụta ihe mgbagwoju anya iji kwalite arụmọrụ ya na ngwa ngwa.

Methyl hydroxyethyl cellulose (MHEC) egosila ụdị ngwa ngwa dị iche iche n'ọtụtụ ụlọ ọrụ na-eme ka ọ dị mma, njigide mmiri, ihe nkiri na-emepụta ihe na ihe ndị na-edozi ahụ. Ọ na-arụ ọrụ dị mkpa na ihe owuwu ụlọ, mkpuchi, nlekọta onwe onye, ​​ọgwụ, nri na mpaghara ndị ọzọ, na ọganihu nke nkà na ụzụ na mgbanwe nke ahịa ahịa, a na-atụ anya na mpaghara ngwa na nha ahịa nke MHEC ga-anọgide na-amụba.
