I-HPMC (i-CAS: 9004-65-3), njengesongezo esisetyenziswa ngokubanzi kwintsimi yezinto zokwakha, isetyenziselwa ukugcinwa kwamanzi, ukuqina kunye nokuphucula ukusebenza kwemveliso egqityiweyo.Izinga lokugcinwa kwamanzi sesinye sezibonakaliso eziphambili xa khetha i-HPMC ekumgangatho ophezulu, ngoko ke makhe sijonge ngakumbi kwizinto ezichaphazela izinga logcino lwamanzi lwe-HPMC.
1.Idosi ye-HPMC, kunye nokusebenza kwayo kokugcinwa kwamanzi kuhambelana ngokuthe ngqo nesixa esongezelelweyo. Isixa se-HPMC esisetyenziswa kwizinto zokwakha kwimarike siyahluka ngokuxhomekeke kumgangatho. Ngokuqhelekileyo yongezwa kwizinto ezifana ne-bonding, i-plastering, i-anti-cracking mortar, njl njl. Imali eyongeziweyo ngokubanzi yi-2 ~ 2.5 KG / MT, inani elongezelelweyo le-putty njl. liphakathi kwe-2 ~ 4.5 KG / MT, i-tile glue phakathi kwe-3.5 ~ 4 KG / MT, kunye nomthamo we-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, kunye ne-ETICS iphakathi kwe-4 ~ 7 KG/MT. Ngaphakathi kolu luhlu, ngakumbi i-HPMC yongezwa, ukugcinwa kwamanzi kuya kuba ngcono.
2.Impembelelo yendawo yokwakha. Ukufuma komoya, ubushushu, uxinzelelo lomoya, isantya somoya kunye nezinye izinto ziya kuchaphazela izinga lokuguquguquka kwamanzi kudaka lwesamente kunye neemveliso ezisekwe kwigypsum. Ngamaxesha ahlukeneyo kunye nemimandla eyahlukeneyo, izinga lokugcinwa kwamanzi kwimveliso efanayo liya kuhluka, kodwa ngokubanzi, Ubushushu bunempembelelo enkulu kwizinga lokugcinwa kwamanzi, ngoko kukho umbono kwimarike: I-HPMC eneqondo lokushisa eliphezulu lejeli liphezulu. -umgangatho wemveliso enezinga eliphezulu lokugcinwa kwamanzi.
3.Inkqubo yokuvelisa kunye ne-viscosity ye-cellulose ether -HPMC. Amaqela e-methoxy kunye ne-hydroxypropoxy ahanjiswa ngokulinganayo kunye ne-cellulose molecular chain, enokunyusa ukudibanisa kwee-athomu ze-oksijini kwi-hydroxyl kunye ne-ether bonds ngamanzi. Ukukwazi ukubopha i-hydrogen kwenza amanzi asimahla abe ngamanzi abophekileyo, ngaloo ndlela alawule ngokufanelekileyo ukuvela kwamanzi abe ngumphunga kunye nokugcina ukugcinwa kwamanzi aphezulu.
Xa i-viscosity ye-HPMC inyuka, izinga lokugcinwa kwamanzi liyanda, i-viscosity ifikelela kwinqanaba elithile, izinga lokugcinwa kwamanzi liyenyuka. Ithande ukuba flat. Isishwankathelo esilula. Umsebenzi wokugcinwa kwamanzi we-HPMC uchatshazelwa yiyo yonke imiba. Ukhetho alukwazi ukusekwa kwisalathisi esinye.
