(1) Ukuzimisela kwe-viscosity: imveliso eyomileyo ilungiselelwe kwisisombululo samanzi kunye noxinzelelo lwesisindo se-2 ° C, kwaye ilinganiswa ne-ndj-1 i-viscometer ejikelezayo;
(2) Ukubonakala kwemveliso ngumgubo. Imveliso ekhawulezileyo ifakwe ngo-“s” kwaye imveliso yodidi loxubo-mayeza ifakwe ngo-“y”. Ngokomzekelo, i-me-4000s yimveliso esheshayo ye-me-4000.
01. Indlela yokusebenzisa i-hydroxypropyl methylcellulose
Yongeza ngokuthe ngqo ngexesha lemveliso, le ndlela yeyona ndlela ilula kwaye imfutshane ithatha ixesha, amanyathelo athile ngala:
1. Yongeza umlinganiselo othile wamanzi abilayo kwisitya esishukumisayo kunye noxinzelelo oluphezulu lwe-shear (imveliso ye-hydroxyethyl cellulose i-soluble emanzini abandayo, ngoko yongeza nje amanzi abandayo);
2. Vula ukuvuselela ngesantya esiphantsi, kwaye ucofe ngokukhawuleza imveliso kwisitya esishukumisayo;
3. Qhubeka uvuselela de onke amaqhekeza afakwe;
4. Yongeza inani elaneleyo lamanzi abandayo kwaye uqhubeke uvuselela de kube zonke iimveliso zichithwa ngokupheleleyo (ukubonakala kwesisombululo kwandisa kakhulu);
5. Emva koko yongeza ezinye izithako kwifomula.
Lungisa utywala bukamama ukuze busetyenziswe: Le ndlela kukwenza imveliso ibe butywala bukamama obunogxininiso oluphezulu kuqala, emva koko bongeze kwimveliso. Inzuzo kukuba inokuguquguquka okukhulu kwaye inokongezwa ngokuthe ngqo kwimveliso egqityiweyo. Amanyathelo afana namanyathelo (1-3) kwindlela yokongeza ngokuthe ngqo. Emva kokuba imveliso imanziswe ngokupheleleyo, yiyeke imele ukupholisa kwendalo ukuba inyibilike, kwaye emva koko ushukumise ngokupheleleyo phambi kokusetyenziswa. Kufuneka kuqatshelwe ukuba i-agent ye-antifungal kufuneka yongezwe kumama otywala ngokukhawuleza.
Ukuxuba okomileyo: emva kokuxuba ngokupheleleyo ukuxuba imveliso yomgubo kunye nezixhobo zomgubo (ezifana nesamente, i-gypsum powder, udongwe lwe-ceramic, njl.), yongeza umlinganiselo ofanelekileyo wamanzi, uxoke kwaye ugxobhoze de imveliso ichithwe ngokupheleleyo.
Ukutshatyalaliswa kweemveliso ezinyibilikayo zamanzi abandayo: iimveliso ezinyibilikayo zamanzi abandayo zinokudibaniswa ngokuthe ngqo kumanzi abandayo ukuze zichithwe. Emva kokongeza kumanzi abandayo, imveliso iya kutshona ngokukhawuleza. Emva kokuba umanzi ixesha elithile, qalisa ukugubha de unyibilike ngokupheleleyo.
02. Amanyathelo okhuseleko xa ulungiselela izisombululo
(1) Iimveliso ezingenalo unyango olungaphezulu (ngaphandle kwe-hydroxyethyl cellulose) aziyi kuchithwa ngokuthe ngqo emanzini abandayo.
(2) Kufuneka ihluzwe kancinane kwisitya sokuxuba, ungafaki ngokuthe ngqo isixa esikhulu okanye imveliso eyenziwe kwibhloko kwisitya sokuxuba.
(3) Ubushushu bamanzi kunye nexabiso le-ph lamanzi linobudlelwane obucacileyo kunye nokuchithwa kwemveliso, ngoko ke ingqwalasela ekhethekileyo kufuneka ihlawulwe.
(4) Musa ukongeza izinto zealkaline kumxube phambi kokuba umgubo wemveliso ugalelwe ngamanzi. Ukunyusa i-pH emva kokumanzisa kuya kunceda ukunyibilika.
(5) Kangangoko kunokwenzeka, yongeza i-agent ye-antifungal kwangaphambili.
(6) Xa usebenzisa iimveliso eziphezulu ze-viscosity, ubunzima bobunzima botywala bomama akufanele bube ngaphezu kwe-2.5-3%, ngaphandle koko utywala oomama buya kuba nzima ukuphatha.
(7) Iimveliso eziye zachithwa ngokukhawuleza aziyi kusetyenziswa ekutyeni okanye kwiimveliso zamayeza.
