HydroxyPropy cellulose tuaj yeem txhim kho cov kev rho tawm tsis kam ntawm cov cement cug

Kev tawm tsam yog ib qho tseem ceeb ntsuas ntsuas qhov zoo ntawm anti - dispersant. HydroxyPropy cellulose yog dej-soluble polymer compound, tseem hu ua dej-soluble cob lossis dej-soluble polymer. Nws nce qhov sib xyaw ua ke ntawm cov sib tov los ntawm kev nce qib ntawm cov dej sib tov. Nws yog ib hom ntawm hydrophilic cov khoom, uas tuaj yeem yaj nyob hauv dej thiab ua cov tshuaj daws teeb meem lossis cov kua tawg. Kev sim qhia tias thaum tus nqi ntawm naphthalene system superplastalizer nce ntxiv ntawm cov cortent tshiab tshiab. Qhov no yog vim tias Naphhalene series siab txuag tus neeg sawv cev ntawm cov khoom noj khoom haus dej ntawm cov khoom noj khoom haus ntawm cov dej xis, thaum cov khoom siv hluav taws xob hauv qab, thaum cov khoom siv hluav taws xob hauv qab, thaum cov khoom siv hluav taws xob nrog cov khoom noj khoom haus ntawm cov dej xis, thaum cov khoom siv hluav taws xob hauv qab, thaum cov khoom siv hluav taws xob nrog cov khoom noj khoom haus ntawm cov dej xis. Nyob rau tib lub sijhawm, nws pom tias nrog kev nce HPMC cov ntsiab lus, cov anti dispersion ntawm tshiab cug cap yog qhov zoo dua thiab zoo dua.

Lub zog cov yam ntxwv ntawm cov pob zeb ua:

HPMC Underwater Qhob admixture tau thov rau hauv lub cav uas engineering ntawm kev nthuav dav, thiab kev tsim lub zog yog C25. Tom qab ntsuas yooj yim, cov kev siv tshuaj makent yog 400kg, cov qhob noom cum kev sib xyaw ua ke yog 0.42, lub zog ntawm cov dej xis yog 42.6MPA, lub zog nruab nrab ntawm Lub hauv qab dej nchuav ua ke nrog kev poob siab ntawm 60mm hauv dej yog 36.4MPA rau hauv huab cua yog 84.8%, uas qhia tias muaj cov nyhuv tseem ceeb.

1. Qhov kev sib ntxiv ntawm HPMC muaj qhov pom tseeb retarding cuam tshuam ntawm coll sib xyaw. Nrog rau kev nce HPMC ntau npaum li cas, lub sijhawm teem lub sij hawm cug yog lub sijhawm ntev. Raws li tib qho xwm txheej ntawm HPMC ntau npaum li cas, lub sij hawm teeb lub sij hawm underwater tshuaj ntev ntev tshaj li ntawm huab cua. Cov yam ntxwv no tau txais txiaj ntsig rau hauv qab dej ua ke twj tso kua mis.

2, tov nrog hydroxypropal methyl cellulose ntawm tshiab cephars muaj cohesion zoo, yuav luag tsis muaj los ntshav tshwm sim.

3, HPMC noj thiab tshuaj khib dej xav tau ua ntej poob thiab tom qab nce ntau.

4. Qhov txuam nrog cov roj reducer txhim kho cov teeb meem ntawm kev nce dej cug, txwv tsis pub nws yuav muaj cov dej hauv qab no ntawm cov ceg tawv xis.

5. Muaj me ntsis sib txawv hauv HPMC sib xyaw ci ntsa iab thiab cov hnoos qeev thiab kev sib cav sib ceg, thiab muaj huab cua nyob rau sab qab ceeb qaub. Lub 28D Underwater cov hnoos qeev yog qhov xoob xoob me ntsis. Qhov laj thawj tseem ceeb yog qhov ntxiv ntawm HPMC ntau ntau txo qhov poob thiab dispersion ntawm cov hmoov av pouring, tab sis kuj tseem ua kom muaj kev sib xyaw ua ke xis mas. Hauv txoj haujlwm, hauv qab cov xwm txheej ntawm kev ua kom muaj kev cuam tshuam hauv qab dej tsis-dispersion nyhuv, cov kev sib xyaw HPMC raug txo kom deb li sai tau.

6, ntxiv HPMC Underwater tsis disthais cov tub ua vaj tse admixture, sib sau ua ke ntawm cov cua yog 84.8%, cov nyhuv muaj txiaj ntsig ntau dua.
