Ubudlelwane phakathi kweViscosity kunye noBushushu beHydroxypropyl Methyl Cellulose (HPMC)

(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, kwaye imveliso esheshayo ifakwe "s".

Uyisebenzisa njani ihydroxypropyl 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 esixutywe kunye noxinzelelo oluphezulu lwe-shear (imveliso ye-hydroxyethyl cellulose i-soluble emanzini abandayo, ngoko yongeza 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, umgubo wegypsum, udongwe lwe-ceramic, njl.), yongeza umlinganiselo ofanelekileyo wamanzi, uxoke kwaye ushukumise de imveliso inyibilike ngokupheleleyo.

Ukutshatyalaliswa kweemveliso ezinyibilikayo zamanzi abandayo: iimveliso ezinyibilikayo zamanzi abandayo zinokudibaniswa ngokuthe ngqo kumanzi abandayo ukuze zichithwe.Emva kokongeza amanzi abandayo, imveliso iya kucwila ngokukhawuleza.Emva kokuba umanzi ixesha elithile, qala ukugubha de unyibilike ngokupheleleyo.

Izilumkiso xa ulungiselela izisombululo

(1) Iimveliso ezingenalo unyango olungaphezulu (ngaphandle kwe-hydroxyethyl cellulose) aziyi kuchithwa ngokuthe ngqo emanzini abandayo;

(2) Kufuneka ihlulwe ngokucothayo kwisitya sokuxuba, ungafaki ngokuthe ngqo isixa esikhulu okanye imveliso eyenze ibhloko kwisitya sokuxuba;

(3) Ubushushu bamanzi kunye nexabiso le-ph lamanzi linobudlelwane obucacileyo kunye nokuchithwa kwemveliso, ngoko ke ingqwalasela eyodwa kufuneka ihlawulwe;

(4) Musa ukongeza ezinye izinto zealkaline kumxube phambi kokuba umgubo wemveliso ufakwe emanzini, kwaye unyuse ixabiso le-ph emva kokuba lifakwe emanzini, eliya kunceda ukunyibilika;

(5) Kangangoko kunokwenzeka, yongeza i-agent ye-antifungal kwangaphambili;

(6) Xa usebenzisa iimveliso ze-viscosity ephezulu, ubunzima bobunzima botywala bomama akufanele bube ngaphezu kwe-2.5-3%, ngaphandle koko utywala oomama kuya kuba nzima ukusebenza;

(7) Iimveliso eziye zachithwa ngokukhawuleza aziyi kusetyenziswa ekutyeni okanye kwiimveliso zamayeza.
