Hydroxypropyl methyl setelise ye-ether (i-HPMC)

Iimbonakalo:
① Ngokugcina amanzi kakuhle, ukuqina, i-RHOOLOGY NE-RHOOLOGY NEZOBUCHULE, SISITHUBA EZIZODWA ZOKWENZA ISIQINISEKISO SOKUKHANYA ZOKUFUNDA UMGANGATHO WOKWENZIWA KOMSEBENZI WOKWENZA IZIBHENO ZOKUFUNDA NOKUFUNDA.
Uluhlu lwePristic Uluhlu lweendlela: Ngenxa yamabakala apheleleyo, inokusetyenziswa kuzo zonke izinto zokwakha zomgubo. 
I-Dosage ye-Dosage: 2-3 kg nganye ye-pon yezinto zokwakha zomgubo ngenxa yomgangatho ophezulu.
Ukuxhaswa kweqondo lobushushu obuphezulu: Iqondo lokugcina amanzi leemveliso ze-HPMC JPMC ziya kuncipha ngokunyuka kobushushu. Ngokwahlukileyo, iimveliso zethu zinokwenza udaka lunenqanaba eliphezulu lokugcina amanzi xa iqondo lobushushu lifikelela kwi-30-40 ° C. Ukugcinwa kwamanzi okuzinzileyo nakwiqondo lokushisa eliphezulu iiyure ezingama-48.
I-⑤good solula: Kubushushu begumbi, yongeza amanzi kwaye uvuselela imizuzu emi-5, vumela ukuba ihlale imizuzu embalwa, emva koko ivuselele ukunyibilikisa. Ukupheliswa kuyakhawuleziswa kwi-PH8-10. Isisombululo sibekwa ixesha elide kwaye sinozinzo oluhle. Kumxube owomileyo, isantya sokusasazeka kunye nokunyibilika emanzini kubaluleke kakhulu.

Indima ye-HPMC ngodaka lomgubo owomileyo

Ngomgubo owomileyo, uMethyl Selete Fely udlala indima yokugcina amanzi, ukuthambisa nokuphucula ukusebenza kokwakha. Umsebenzi wokugcina amanzi ofanelekileyo uqinisekisa ukuba udaka aluyi kubangela isanti, i-powding kunye nokuncitshiswa kwamandla ngenxa yokunqongophala kwamanzi kunye nokungaphelelanga kwesamente; Isiphumo sokuthambisa isiphumo sandisa amandla olwakhiwo lodaka olumanzi, kunye nokongezwa kwe-methyl seluplose i-ether inokuthi iphucule udaka olumanzi lodaka olumanzi, ngaloo ndlela iphucule udaka olunamanzi eludongeni nasekunciphiseni inkunkuma.

Ngokubanzi, ukuphakama kwe-viscosity, eyona nto ilunge ngakumbi. Nangona kunjalo, ukuphakama okuphezulu, ukuphakama kobunzima be-MC, kunye nokuzalwa kwayo kuya kuncitshiswa, okunokuba nefuthe elibi kumandla kunye nokusebenza komsebenzi wokwakha. Ukuphakama kwe-viscofity, eyona nto icacileyo yokuthambisa kodaka, kodwa ayifani ngokuthe ngqo. Ukuphelisa i-viscofity, kokukhona u-viscous olona dumo lwamanzi luya kuba. Ngexesha lokwakha, lubonakaliswa njengokunamathela kumhlambi kunye nokunamathela okuphezulu kweyona ndawo. Kodwa akuncedi ukonyusa amandla olwakhiwo lofudu lwamanzi.

Iipropathi zomzimba kunye neekhemikhali:

Imbonakalo: imbonakalo
I-2. Ubungakanani bentsumpa: 80-100 Mesh inqanaba elingaphezulu kwe-98.5%; Ireyithi ye-Mesh ye-mesh ye-100%.

I-6. Ingxwabangxwaba yomhlaba ophezulu: 2% Isisombululo esiyi-ACTEAROOR yi-42-56DYN / CM3.
7. Inyibilikiswe emanzini kunye nezinye izinyibilikisi, ezinje nge-ethanol / amanzi, i-propanol / amanzi, i-trichloroethane, njl. Njl. Izisombululo ze-ACTE zisebenza. Ukungafihlisi ngendlela esibonakalayo kunye nokusebenza ngokuzinzileyo. Ukucaciswa okwahlukileyo kweemveliso kunamaqondo obushushu ahlukeneyo egesi, kwaye u-Soluba uza kutshintsha nothando. Ezantsi kokufakwa kwe-viscosity, kokukhona ukonakala. Inkcazo eyahlukeneyo ye-HPMC inomahluko othile kwintsebenzo, kwaye ukuchithwa kwe-HPMC emanzini akuchaphazeli kwixabiso le-pH.
8. Ngokuncitshiswa kwemixholo ye-APELYL, i-gell inyuka, ukuvela kwamanzi kwe-HPMC kuyancipha, kwaye umsebenzi womhlaba uyancipha.
9. I-HPMC ikwanazo iimpawu zobuchule bokuthandwa, ukumelana netyuwa, ukugcinwa kwamanzi, ukuzinza kwamanzi, uzinzo lwefilimu, kunye nokusasazeka kwelitha.

Eyona njongo iphambili:

1. Ishishini lokwakha: Njengearhente yokugcina amanzi kunye nokubuyela umva ngenxa yokucheba kwesamente, inokwenza isidumbu siphambuke. Isetyenziswe njenge-binder kwi-plaster, i-Plaster, i-popder okanye ezinye izinto zokwakha ukuphucula ukusasazeka kunye nexesha lomsebenzi. Ingasetyenziswa njengencamathisi ye-tile, imabula, umhlobiso weplastiki, encamathisela ukuqiniswa, kwaye unokunciphisa nenani lesamente. Ukugcinwa kwamanzi e-HPMC kuthintela ukuthambisa ukusuka ekuqhekekeni ngenxa yokomisa ngokukhawuleza emva kokufaka isicelo, kwaye kuphucula amandla emva kokukhula.

Ungayichitha njani kwaye uyisebenzise:

1. Thatha i-1/3 okanye i-2/3 yexabiso elifunekayo lamanzi ashushu kwaye ushiyeke ngaphezulu kwe-85 ° C, yongeza i-cleculose ukufumana amanzi ashushu, emva koko yongeza umxube osisiphumo.
2. Yenza i-Porridge-njengeSute-tyutyhatshwe i-HPMC ngotywala obunqabileyo (indlela iyafana nangasentla), yongeza amanzi abandayo kwaye uqhubeke nokuvuselela.
I-3. Ukusetyenziswa okuxubeneyo: Ngenxa yokungqinelana okugqwesileyo kwe-HPMC, kungadityaniswa lula ne-cement, i-gypsim powder, i-pigs kunye nefuthe elifunekayo.

Ukupakisha, ukugcinwa kunye nokuThutha amanyathelo okhuseleko:

Ipakishwe kwiplasitiki yephepha okanye kwikhadibhodi yekhadibhodi edityaniswe ngeengxowa zeplasitiki zePolythylene, ubunzima be-NET kwingxowa nganye: 25kg. Itywinwe ukuba igcinwe. Khusela elangeni, imvula kunye nokufuma ngexesha lokugcina kunye nokuhamba.
