Hydroxypropyl methyl seluplose(i-HPMC)isetyenziswa ngokubanzi kwi-posty powder enomgubo we-100000, ngelixa udaka luneemfuno eziziimfuno eziphakamileyo kuhlobo lwe-viscosity kwaye kufuneka zikhethwe ngohlobo lwe-150000 lokusebenzisa ngcono. Owona msebenzi ubalulekileyohydroxypropyl methyl seluplosekukugcina amanzi, ulandelwe ngokutyibilika. Ke ngoko, kwi-putty powder, logama nje ukufikelelwa kwamanzi kwaye i-vickosity isezantsi, kunokwenzeka. Ngokubanzi, ukuphakama kwamehlo, kungcono ukugcinwa kwamanzi. Nangona kunjalo, xa i-viscosity idlula i-100000, isiphumo sokubonisa ukugcinwa kwamanzi akubalulekanga.

I-JUSufu yezakhiwoHydroxypropyl methyl seluploseUkwahlulwa nguVeksity, ngokubanzi yahlulwe yangama-

1. I-Viscofity ephantsi: I-400 Vilosity sellity, ikakhulu isetyenziselwa ukungazithembi. Uhlobo oluphantsi, ukuqukuqela okuhle, kwaye emva kokongezwayo, kuya kulawula ukugcinwa kwamanzi okungaphezulu. Ukopha akubonakali, i-shrinkage incinci, kwaye ukuqhekeka kuncitshisiwe. Ingakwazi ukuxhathisa i-sediment, ukomeleza ukungakwazi nokukhumbula i-pumes.
I-2. Ngaphakathi ukuya kwi-Viscofity ephantsi: 20000 ukuya kwi-50000 ye-villasity sellity, ikakhulu isetyenziselwa iimveliso zeGyppum kunye neefilimu ezidibeneyo. I-viscosity ephantsi, ukugcinwa kwamanzi kakuhle, ukusebenza kakuhle, kunye nokudibanisa amanzi aphantsi,
I-3. I-vissium ephakathi: 75000-100000 I-viscofity yeselula, ubukhulu becala isetyenziselwa i-interm kunye ne-ifakeli yangaphandle. UVIKELWANA WOKUGQIBELA WOKUGQIBELA, UKUGCINWA KWAMANZI, NOKWENZA IDLULEKILEYO YOKUQESHWA.
4. Uhlobo oluphezulu: I-150000 ukuya kwi-200000 Yuan, ikakhulu isetyenziselwa i-polystyrene ye-polystyrene ye-polystrene ye-polystyrene, i-bad bad bad babysity ye-viscosity kunye nokugcinwa kwamanzi. Udaka akukho lula ukuwa kwaye uxhonywe, uphucule ulwakhiwo.
Ngokubanzi, ukuphakama kwamehlo, kungcono ukugcinwa kwamanzi. Ke ngoko, abathengi abaninzi bakhetha ukusebenzisa i-viscosity ye-vissity (75000-100000) endaweni ye-vissium ye-villase (ngo-20000-50000) ukunciphisa isixa songezelelo kunye nokulawula iindleko.
I-vickosity yeI-HPMCIlinganayo ngokulinganayo ubushushu, ngamanye amagama, uVenkile unyuka ngokuhla kweqondo lobushushu. I-viscosity yemveliso kuthetha ukuba isisombululo se-2% kwiqondo lobushushu le-20 degrees Celsius, kwaye iziphumo zovavanyo zichanekile.
Kwizicelo ezithile, ingqalelo kufuneka ihlawulwe kwiindawo ezinomahluko omkhulu weqondo umahluko phakathi kwehlobo nobusika, kwaye kuyacetyiswa ngamandla ukusebenzisa i-viscofity esezantsi ebusika. Ngaphandle koko, ukuba i-vickosity iphantsi, i-viscosity yeselselose iya kukhula kwaye ukukrwada kuya kuba nzima.
