I-Hydroxypropyl methyl cellulose iyi-nonionic cellulose ether ekhiqizwa kukotini ohlanziwe ngochungechunge lwezinqubo ze-etherification. Ukusebenza kwayo okuyinhloko ukulandelayo:

1. I-HPMC iyimpuphu emhlophe noma ephuzi kancane. kunganephunga, akunabuthi

2. I-HPMC ingahlakazeka masinyane emanzini abandayo ukwenza isixazululo esibonakalayo se-viscous; Ngoba iqukethe inani elithile leqembu le-hydrophobic methoxy, lingaqhekeka kwezinye izinyibilikisi eziphilayo.

3. I-viscosity yesisombululo samanzi se-HPMC izinze kakhulu ku-PH3.0-10.0. Lapho inani le-PH lingaphansi kuka-3 noma ngaphezulu kuka-10, i-viscosity izoncishiswa kakhulu

4. Isixazululo samanzi se-HPMC sinomsebenzi ongaphezulu komhlaba, ngakho-ke siye saqina futhi sivikela ukuqina kwesiqu se-colloid

5. Ukusetshenziswa kokuwashwa kwamanzi ashisayo nokucwengwa kahle ngesikhathi senqubo yokulungiselela kuholele kokuqukethwe komlotha ophansi

6. I-HPMC i-hydrophilic, ingezwe kudaka, i-gypsum, upende neminye imikhiqizo ukuze idlale indima ephezulu yokugcina amanzi

7. I-HPMC inokumelana okuhle nokuqina okuqinile kokuqina kwesitoreji sesikhathi eside

8. I-HPMC inganciphisa ukungqubuzana kokulingana futhi ithuthukise ukuthambisa kokwakha

9. I-HPMC ingakhiqiza ishidi elibonakalayo eliqinile neliguquguqukayo ngamafutha amahle nokumelana ne-ester

* usimende wokufakelwa okushisayo, ukunamathela kwe-ceramic tile, ukuhlangana okuhlanganayo, i-stucco jypsum, udaka;

* i-ejenti yokuqina yokupeyinta, i-ejenti yokusabalalisa kanye ne-stabilizer;

* Imboni ye-ink njenge-ejenti yokuqina, i-ejenti yokusabalalisa kanye ne-stabilizer;

* I-plastiki yakha i-ejensi yokukhipha isikhunta, ukuthambisa, izithako;

* usimende, imikhiqizo yesibili ye-gypsum;

* imoto, isepha

Isicelo:

1. I-putty yangaphakathi nodonga lwangaphandle

Indawo yokugcina amanzi ye-HPMC yenza i-putty powder ngeke iqhekeke ngenxa yokoma ngokushesha okukhulu ngemuva kokwakhiwa, ithuthukise amandla ngemuva kokuqina.Ngaso leso sikhathi ibuye ibambe iqhaza elisizayo ekwenzeni ngcono isibopho

2. Uhlelo lwangaphandle lokufakelwa odongeni

Ukungezwa kwe-HPMC kungathuthukisa amandla e-bond kanye nokubusheleleka kodaka futhi kuthuthukise ukusebenza kahle komsebenzi

3. Udaka oluhlanganisiwe

Ukugcinwa kwamanzi okuhle kwe-HPMC, kungaba nesikhathi esinde sokwakha, ukuvimbela ithayela le-ceramic ukuthi lilahlekelwe amanzi ngokushesha okukhulu kuholele ekuweni, kuthuthukise amandla ebondweni namandla we-shear

4. Ukulolongwa kwesisekelo seGypsum nemikhiqizo

Ukumelana nokulengiswa kwe-HPMC kungaqeda ukuqhuma kwesakhiwo futhi kufake ukumboza okujiyile

5. Ukufakwa kwemishini yokufafaza ngomshini

HPMC kungaba ngcono fluidity odakeni, lula ukudluliswa futha, ugweme nosimende stratification futhi ipayipi wokufaka

6. Ishidi likakhonkolo extruded (wallboard engasindi)

I-HPMC ingathuthukisa impahla enamathela eshidi le-gypsum ngemuva kokukhipha, ithuthukise amandla e-bond kanye nokuthambisa, futhi iqinisekise amandla

7. Ukuzilinganisa ngodaka

I-viscosity ephansi i-HPMC inamandla okumelana nemvula futhi ithuthukise ukugeleza kodaka. Ukugcinwa kwayo kwamanzi kuvimbela ukuqhekeka nokuncipha

Ukupakisha / Ukuhamba

Imikhiqizo ifakwe emigqonyeni yolukhuni eyenziwe nge-polypropylene enezikhwama zangaphakathi zepolythene ezihlanganiswe nepulasitiki, ezinesisindo esingu-25kg ngesikhwama ngasinye.Bhekisisa imvula nokuvikelwa yilanga ngesikhathi sokuhamba.
