I-Putty luhlobo lwezixhobo zokuhombisa izakhiwo. Umaleko we-putty emhlophe phezu kwegumbi elingenanto osandul’ ukuthengwa udla ngokuba mhlophe ngaphezu kwama-90 kwaye ube mhle ngaphezu kwama-330. I-Putty yahlulwe yaba ludonga lwangaphakathi nodonga lwangaphandle. I-putty yangaphandle yodonga kufuneka imelane nomoya nelanga, ngoko ke ineglu ephezulu, amandla aphezulu kunye nesalathisi sokhuseleko lokusingqongileyo esiphantsi kancinci. Isalathisi esibanzi se-putty yodonga lwangaphakathi silungile, sisempilweni kwaye sikhuselekile kokusingqongileyo, ngoko ke udonga lwangaphakathi alusetyenziswa ngaphandle kwaye udonga lwangaphandle alusetyenziswa ngaphakathi. Ngokwesiqhelo i-putty isekelwe kwi-gypsum okanye kwisamente, ngoko ke umphezulu urhabaxa kwaye kulula ukuwubopha ngokuqinileyo. Nangona kunjalo, ngexesha lokwakha, kusafuneka kusetyenziswe umaleko we-interface agent kwisiseko ukuze kutywinwe isiseko, kwaye kuphuculwe ukunamathela kodonga, ukuze i-putty ikwazi ukubotshelelwa ngcono kumphezulu wesiseko.
Ubungakanani be-HPMC esetyenziswa ngokwenene buxhomekeke kwimeko-bume yemozulu, umahluko wobushushu, umgangatho we-calcium ash powder yendawo, iresiphi eyimfihlo ye-putty powder kunye "nomgangatho ofunekayo ngumsebenzisi". Ngokubanzi, phakathi kwe-4kg kunye ne-5kg.
I-HPMC inomsebenzi wokuthambisa, onokwenza ukuba umgubo we-putty usebenze kakuhle. I-Hydroxypropyl methylcellulose ayithathi nxaxheba kuyo nayiphi na i-compound reaction, kodwa inefuthe loncedo kuphela. Umgubo we-putty luhlobo lwe-compound reaction kumphezulu wamanzi naseludongeni,
Ezinye iingxaki:
1. Ukususwa komgubo we-putty
A: Oku kunxulumene nomthamo we-calcium yelayimu, kwaye kunxulumene nomthamo kunye nomgangatho we-cellulose, obonakala kwizinga lokugcina amanzi kwimveliso. Izinga lokugcina amanzi liphantsi kwaye ixesha lokufuma kwe-calcium yelayimu alanele.
2. Ukuxobula nokuqengqa umgubo we-putty
A: Oku kunxulumene nesantya sokugcina amanzi. I-cellulose viscosity iphantsi, nto leyo elula ukuyenza okanye idosi incinci.
3. Incopho yenaliti yomgubo we-putty
Oku kunxulumene ne-cellulose, eneempawu ezimbi zokwenza ifilimu. Kwangaxeshanye, ukungcola kwi-cellulose kunempendulo encinci kunye ne-calcium yomlotha. Ukuba impendulo inamandla, umgubo we-putty uya kubonisa imeko ye-tofu residue. Ayinakuya eludongeni kwaye ayinamandla okubopha. Ukongeza, ikwafumaneka nakwiimveliso ezifana namaqela e-carboxy axutywe kwi-cellulose.
