Polycarboxylic acid high efficiency dej txo tus neeg sawv cev ua haujlwm:
1. Cov qauv tshwj xeeb molecular thiab tshwj xeeb ceg qauv tsim, uas yog siv rau hydrolysis cov tshuaj tiv thaiv hauv cov pob zeb tshiab.Los ntawm kev kho cov ceg qauv, tus nqi hydrolysis tuaj yeem hloov kho nyob rau hauv lub sijhawm zoo kom ua tiav cov kev tiv thaiv xaiv.
2. Cov cuab yeej tso tawm qeeb qeeb, cov khoom no yog sib xyaw rau hauv pob zeb, maj mam hydrolyzed, tso cov carboxylic acid pawg kom ua tiav cov nyhuv dispersion ntev, ua tiav cov txiaj ntsig zoo khaws cia.
3. Lub zog nce siab dua, cov pob zeb sib xyaw nrog cov khoom tsis hloov lub sijhawm teeb tsa, kov yeej qhov tsis txaus ntawm qhov kev rov ua haujlwm dav dav kom ua kom cov pob zeb zaum kawg lub sijhawm ntev dhau lawm, thiab kev txhim kho lub zog thaum ntxov yog qeeb heev.
Kev cuam tshuam ntawm PH tus nqi ntawm polycarboxylic acid dej txo tus neeg sawv cev:
1. Nrog rau qhov nce ntawm PH tus nqi, lub zog compressive piv ntawm cov qhob nyhav nce me ntsis, tab sis lub zog tsis hloov pauv loj nyob rau theem tom qab.
2. Nrog rau qhov nce ntawm PH tus nqi, qhov pib txo tus nqi ntawm cov pob zeb tsis muaj kev hloov pauv, tab sis qhov poob qis thiab nthuav dav ntawm cov pob zeb ua kom pom tseeb tom qab ib teev poob.
3. Nrog rau qhov nce ntawm PH tus nqi, cov roj cov ntsiab lus ntawm cov pob zeb tsis muaj qhov pom tseeb hloov pauv, tab sis cov viscosity ntawm cov pob zeb nce ntxiv thiab cov dej ntws tawm txo qis.
4. Nrog rau qhov nce ntawm PH tus nqi, lub zog compressive piv ntawm cov pob zeb nce me ntsis thaum muaj hnub nyoog, tab sis lub zog tsis hloov pauv loj tom qab theem.
Cov yam ntxwv ntawm cov khoom:
1. Tus nqi txo dej siab
2. Zoo adhesion
3. Muaj zog loj hlob tus nqi
4. Lub zog zoo thiab kav ntev
5. Zoo adaptability
6. Ntsuab: tsis muaj formaldehyde thiab lwm yam khoom xyaw.
Cov kev ceev faj:
1. Cov khoom no yog non-toxic thiab harmless, biodegradable, tab sis tsis edible.
2. Yog tias nws nkag mus rau hauv lub qhov muag, nws yuav tsum tau yaug nrog dej kom ntau rau lub sijhawm.
3. Yog tias koj ua rau muaj kev fab tshuaj rau ib feem ntawm tib neeg lub cev, koj yuav tsum sab laj nrog kws kho mob raws sijhawm.
