I-HPMC (CAS:9004-65-3), njengesongezelelo esisetyenziswa kakhulu kwicandelo lezixhobo zokwakha, isetyenziselwa kakhulu ukugcina amanzi, ukuqina kunye nokuphucula ukusebenza kakuhle kwemveliso egqityiweyo. Izinga lokugcina amanzi lelinye lawona mabonakaliso aphambili xa ukhetha i-HPMC ekumgangatho ophezulu, ngoko makhe sijonge ngokusondeleyo izinto ezichaphazela izinga lokugcina amanzi le-HPMC.
1. Umthamo we-HPMC, kunye nokusebenza kwayo kokugcinwa kwamanzi kuhambelana ngokuthe ngqo nobungakanani obongeziweyo. Ubungakanani be-HPMC esetyenziswa kwizixhobo zokwakha ezithengiswayo buyahluka ngokuxhomekeke kumgangatho. Ngokuqhelekileyo yongezwa kwi-bonding, plastering, anti-cracking mortar, njl. Ubungakanani bokongeza ngokubanzi yi-2 ~ 2.5 KG /MT, ubungakanani bokongeza be-putty njl. buphakathi kwe-2 ~ 4.5 KG / MT, i-tile glue iphakathi kwe-3.5 ~ 4 KG / MT, kwaye ubungakanani be-tile grout yi-0.3 ~ 1 KG / MT ngokweendlela ezahlukeneyo zokwakha, ububanzi be-gap kunye ne-slurry fineness, i-self-leveling mortar iphakathi kwe-0.2 ~ 0.6 KG / MT, kwaye i-ETICS iphakathi kwe-4 ~ 7 KG / MT. Ngaphakathi kolu luhlu, okukhona i-HPMC ingaphezulu, ukusebenza kokugcinwa kwamanzi kuya kuba ngcono.
2. Impembelelo yendawo yokwakha. Ukufuma komoya, ubushushu, uxinzelelo lomoya, isantya somoya kunye nezinye izinto ziya kuchaphazela izinga lokuguquguquka kwamanzi kwisamente kunye neemveliso ezisekwe kwi-gypsum. Kwiixesha ezahlukeneyo zonyaka nakwiindawo ezahlukeneyo, izinga lokugcina amanzi kwimveliso efanayo liya kwahluka, kodwa ngokubanzi, Ubushushu bunempembelelo enkulu kwizinga lokugcina amanzi, ngoko ke kukho umbono kwimarike: I-HPMC enobushushu obuphezulu bejeli yimveliso esemgangathweni ophezulu enezinga eliphezulu lokugcina amanzi.
3. Inkqubo yokuvelisa kunye ne-viscosity ye-cellulose ether -HPMC. Amaqela e-methoxy kunye ne-hydroxypropoxy asasazwa ngokulinganayo kwi-cellulose molecular chain, nto leyo enokunyusa unxibelelwano lwee-athomu ze-oxygen kwi-hydroxyl kunye ne-ether bonds namanzi. Amandla e-hydrogen bonding enza amanzi akhululekileyo abe ngamanzi abotshelelweyo, ngaloo ndlela elawula ngempumelelo ukufuma kwamanzi kunye nokufikelela ekugcinweni kwamanzi okuphezulu.
Xa i-viscosity ye-HPMC isanda, izinga lokugcina amanzi nalo liyakhula, i-viscosity ifikelela kwinqanaba elithile, izinga lokugcina amanzi liyakhula. Ihlala ithe tyaba. Isishwankathelo esilula. Umsebenzi wokugcina amanzi we-HPMC uchatshazelwa zizo zonke iinkalo. Ukhetho alunakusekelwa kwisalathisi esinye.
