I-Hydroxypropyl methyl cellulose(hpmc)ngokuqhelekileyo isetyenziselwa i-putty powder kunye ne-viscosity ye-100000, ngelixa udaka luneemfuno eziphezulu ze-viscosity kwaye kufuneka zikhethwe nge-viscosity ye-150000 ukuze zisetyenziswe ngcono. Owona msebenzi ubalulekileyo wei-hydroxypropyl methyl cellulosekukugcina amanzi, kulandele ukujiya. Ngoko ke, kwi-putty powder, ngokude nje ukuba ukugcinwa kwamanzi kufikeleleke kwaye i-viscosity iphantsi, nayo inokwenzeka. Ngokuqhelekileyo, okukhona i-viscosity iphezulu, ngcono ukugcinwa kwamanzi. Nangona kunjalo, xa i-viscosity idlula i-100000, umphumo we-viscosity ekugcinweni kwamanzi ayibalulekanga.

Jufu Building Material GradeHydroxypropyl Methyl CelluloseYahlulwe yi-Viscosity, yohlulwe ngokubanzi kwezi ntlobo zilandelayo:

1. I-viscosity ephantsi: i-cellulose ye-viscosity ye-400, isetyenziselwa ubukhulu becala i-self leveling mortar. I-viscosity ephantsi, ukuhamba kakuhle, kwaye emva kokongezwa, kuya kulawula ukugcinwa kwamanzi angaphezulu. Ukuphuma kwegazi akubonakali, i-shrinkage incinci, kwaye ukuqhekeka kuyancipha. Isenako ukumelana nentlenga, iphucule ukuqukuqela nokumpompa.
2. I-viscosity ephakathi ukuya kwi-low viscosity: i-20000 ukuya kwi-50000 i-viscosity cellulose, eyona nto isetyenziselwa iimveliso ze-gypsum kunye nezihlunu ezidibeneyo. I-viscosity ephantsi, ukugcinwa kakuhle kwamanzi, ukusebenza kakuhle, kunye nokongezwa kwamanzi aphantsi,
3. I-viscosity ephakathi: i-75000-100000 i-viscosity cellulose, isetyenziselwa ikakhulu kwi-putty yangaphakathi nangaphandle yodonga. I-viscosity ephakathi, ukugcinwa kakuhle kwamanzi, kunye ne-drape efanelekileyo yokwakha.
4. High viscosity: 150000 ukuya 200000 yuan, ikakhulu esetyenziselwa polystyrene amasuntswana ukwasulela udaka izinto umgubo, vitrified micro bead insulation udaka kunye viscosity eliphezulu kunye nokugcinwa kwamanzi. Umdaka akulula ukuwa kunye nokuxhoma, ukuphucula ukwakhiwa.
Ngokuqhelekileyo, okukhona i-viscosity iphezulu, ngcono ukugcinwa kwamanzi. Ngoko ke, abathengi abaninzi bakhetha ukusebenzisa i-cellulose ye-viscosity ephakathi (75000-100000) endaweni ye-cellulose ye-viscosity ephakathi (20000-50000) ukunciphisa inani lokongezwa kunye nokulawula iindleko.
I-viscosity yeHPMCihambelana ngokungafaniyo neqondo lokushisa, ngamanye amazwi, i-viscosity iyanda ngokuhla kweqondo lokushisa. I-viscosity yemveliso ithetha ukuba isisombululo sayo se-2% sikwiqondo lokushisa lama-20 degrees Celsius, kwaye iziphumo zovavanyo zichanekile.
Kwizicelo ezithile, ingqalelo kufuneka ihlawulwe kwiindawo ezinomahluko omkhulu wobushushu phakathi kwehlobo nobusika, kwaye kucetyiswa ngamandla ukuba kusetyenziswe i-viscosity ephantsi ebusika. Ngaphandle koko, ukuba i-viscosity iphantsi, i-viscosity ye-cellulose iya kwanda kwaye i-scratches iya kuba nzima.
