Ukusetyenziswa kwe-hydroxypropyl methylcelcelgalose e gypsum

Hydroxypropyl methylcelculose (hpmc)yisongezelelo esetyenziswayo kwizinto zokwakha, ngakumbi kwiimveliso ezisekwe gypsim. I-HPMC inendawo elungileyo yokugcina amanzi, i-tickeng, i-yetha kunye ne-adherion, esenza ukuba ibe yinto engenakuphikwa kwimveliso ye-gypsim.

1. Indima ye-HPMC kwiGypsum

Ukuphucula ukugcinwa kwamanzi

I-HPMC inezinto ezibalaseleyo zokufudukela kwamanzi kunye neepropathi zokugcina amanzi. Ngexesha lokusetyenziswa kweemveliso ze-gypsim, ukongeza isixa esifanelekileyo se-HPMC kungalibazisa ngempumelelo ukuphulukana namanzi, ukuphucula ukusebenza kweGyppum Slarry, kuphephe ukubethelwa ixesha elide ngexesha lokuphuma kwamanzi.

Ukuphucula ububi kunye neepropathi ezichasene ne-anti

I-HPMC inika i-gypsum slurry entle, ivumela ukuba ilandele ngokuqinileyo kwiindonga okanye ezinye izinto. Kwizixhobo ze-gypsim eyakhiwe kumphezulu othe nkqo, isiphumo esibi se-HPMC sinokunciphisa ukuqhutywa kunye nokuqinisekisa ukufana nokucoceka kolwakhiwo.

Ukuphuculwa kwentsebenzo yokwakha

I-HPMC yenza ukuba i-gypsum ilula ukufaka kwaye isasazeke, iphucule ukusebenza ngokukuko, kwaye inciphise inkunkuma ebonakalayo. Ukongeza, inokunciphisa ukuthambeka ngexesha lokwakhiwa, kuyenza kube lula kwaye inyibilike kubasebenzi bokwakha ukuze basebenze.

Ukuphucula ukunganyangeki kwe-rack

Ngexesha lenkqubo yokuhlaselwa kweemveliso ze-gypsim, ukuphuma kwamanzi ngokungafundi kunokubangela ukuqhekeka komhlaba. I-HPMC yenza i-gydration hydration i-iyunifomu engaphezulu yokugcinwa kwayo emanzini, ngaloo ndlela kuncitshiswa kokusekwa kwee-rocks kunye nokuphucula umgangatho wemveliso egqityiweyo.

Impembelelo kwixesha lokudibana

I-HPMC inokwandisa ngokufanelekileyo ixesha elihle leGyppum Slarry, ivumela abasebenzi bokwakha ukuba babe nexesha elaneleyo lokuhlengahlengisa kwaye baphephe ukusilela okukhawulezayo kweGypsim.

2. Ukusetyenziswa kwe-HPMC kwiimveliso ezahlukeneyo ze-gypsim

I-Gypsim Prating

Kwi-Gyppum Frating Izixhobo zokuSebenzisa, owona msebenzi ophambili we-HPMC kukuphucula ukugcinwa kwamanzi kunye nokuphucula ukusebenza kwe-Gypsum, ukuze iGypsum ingalandela ngcono eludongeni, inciphise umgangatho wokwakha.

I-Gyppum Itoty

I-HPMC inokuphucula i-thambisa kwaye igudileyo ye-ITTY, ngelixa iphucula ubumbeleli, esenza ilungele ukukholelwa kakuhle.

Ibhodi yeGyppum

Kwimveliso yeByppmm yeBhodi, i-HPMC isetyenziselwa ukulawula imigangatho ye-hydration, thintela iBhodi ukuba yomile ngokukhawuleza, iphucule umgangatho wemveliso egqityiweyo, kwaye uphucule ukunganyangeki kwe-rack.

I-Gyppum yokuzibandakanya

I-HPMC inokudlala indima eqaqambileyo kwi-Gyppum yokuzibandakanya, ukusinika ulwelo olungcono kunye nozinzo, ukunqanda ukwahlula kunye nokuphucula ukusebenza ngokukuko.

3. Ungayisebenzisa njani i-HPMC

Kukho ezi ndlela zilandelayo ukongeza i-HPMC kwiimveliso ze-gypsim:
Umxube owomileyo ngqo: Hlanganisa i-HPMC ngokuthe ngqo ngezinto ezomileyo ezifana ne-gyppum powder, kwaye yongeza amanzi kunye nokuvuselela kancinci ngexesha lokwakha. Le ndlela ifanelekile kwiimveliso ze-gypsim ezixubeneyo, ezinjenge-gyppum ibeke kunye nezinto zepropathi.

Yongeza emva kokupheliswa kwangaphambili: Dibanisa i-HPMC emanzini kwisisombululo seColoidal kuqala, kwaye uyilonge kwi-gypsim slighty yokusasazeka okungcono kunye nokuchithwa. Ilungele iimveliso ezineemfuno ezithile zenkqubo ekhethekileyo.

4. Ukukhetha kunye nolawulo lwe-HPMC

Khetha i-viscofity efanelekileyo

I-HPMC ineemodeli ezahlukeneyo ze-viscofity, kwaye i-viscofity efanelekileyo inokukhethwa ngokweemfuno ezithile zeemveliso zeGyppum. Umzekelo, i-HPMC ephezulu ye-HPMC ilungele ukunamathela kunye nokuchasana nokuntywila, ngelixa i-HPMC ye-HPMC ilungele kakhulu izixhobo ze-gypsim kunye nolwelo oluphezulu.

Ulawulo olusebenzayo lwesixa sokudibanisa

Isixa se-HPMC esongezwe sihlala siphantsi, ngokubanzi phakathi kwe-0.1% -0.5%. Ukongeza okugqithisileyo kunokuchaphazela ixesha kunye namandla okugqibela eGypsum, ngoko ke kufuneka kulungiswe ngokufanelekileyo ngokweempawu zemveliso kunye neemfuno zokwakha.

Hydroxypropyl methylcelceluploseIdlala indima ebalulekileyo kwimizobo esekwe kwiGyppum. Ayiphumi nje ukugcinwa kwamanzi kunye nokusebenza kokwakha, kodwa kukuphucula ubunamatheko kunye nokunganyangeki, ukwenza iimveliso ze-gypsim azinza ngakumbi kwaye ziqinile. Ukhetho olusebenzayo kunye nokusetyenziswa kwe-HPMC kunokuphucula kakhulu umgangatho weemveliso ze-gypsim kwaye ufezekise iimfuno ezahlukeneyo zokwakha.
