Hydroxypropyl Methyl Cellulose (HPMC)
1. Ndiwokhazikika ku asidi ndi alkali, ndipo njira yake yamadzimadzi imakhala yokhazikika pa pH = 2-12.Koloko ndi madzi a mandimu sakhala ndi zotsatira zambiri pa ntchito yake, koma zamchere zimatha kufulumizitsa kusungunuka kwake ndikuwonjezera kukhuthala kwake pang'ono.
2. HPMC ndi mkulu-mwachangu madzi posungira wothandizila youma ufa matope dongosolo, amene angathe kuchepetsa mlingo wa magazi ndi layering mlingo wa matope, kusintha kugwirizana kwa matope, bwino ziletsa mapangidwe ming'alu pulasitiki mu matope, ndi kuchepetsa pulasitiki. kusweka index of mortar.
3. Ndi electrolyte yopanda ionic komanso yopanda polymeric, yomwe imakhala yokhazikika muzitsulo zamadzimadzi zomwe zimakhala ndi mchere wazitsulo ndi ma electrolyte a organic, ndipo zimatha kuwonjezeredwa ku zipangizo zomangira kwa nthawi yaitali kuti zitsimikizire kuti kukhazikika kwake kumakhala bwino.
4. Ntchito yogwira ntchito ya matope yakhala bwino kwambiri.Mtondo umawoneka ngati "wodzaza mafuta", zomwe zimatha kupangitsa kuti zipinda zapakhoma zikhale zodzaza, zosalala pamwamba, kupanga matope ndi maziko olimba kwambiri, ndikutalikitsa nthawi yogwira ntchito.
kusunga madzi
Kukwaniritsa kukonza kwamkati, komwe kumathandizira kuwongolera mphamvu kwanthawi yayitali
Kuletsa kutuluka kwa magazi, kuteteza matope kuti asakhazikike ndi kutsika
Limbikitsani kukana kwa matope.
kunenepa
Anti-sectional, kulimbikitsa kufanana kwamatope
Imawonjezera mphamvu ya bond yonyowa ndikuwongolera kukana kwa sag.
magazi mpweya
Limbikitsani magwiridwe antchito amatope
Pamene kukhuthala kwa cellulose kumakhala kokulirapo komanso unyolo wa mamolekyulu ndi wautali, mphamvu yolowera mpweya imawonekera kwambiri.
Kuchedwetsa
Synergizes ndi kusunga madzi kuti atalikitse nthawi yotseguka ya matope.
Hydroxypropyl starch ether (HPS)
1. Kuchuluka kwa hydroxypropyl mu wowuma ether kumapangitsa dongosololi kukhala ndi hydrophilicity yokhazikika, kupanga madzi aulere kukhala madzi omangika ndikuchita bwino pakusunga madzi.
2. Ma etha owuma okhala ndi ma hydroxypropyl osiyanasiyana amasiyana pakutha kwawo kuthandiza mapadi posungira madzi mulingo womwewo.
3. The m'malo hydroxypropyl gulu kumawonjezera kukula digiri mu madzi ndi compresses otaya danga la particles, potero kuonjezera mamasukidwe akayendedwe ndi thickening kwenikweni.
mafutatropic mafuta
Kuthamanga kwachangu kwa wowuma etere mu matope dongosolo amasintha rheology matope ndi endows ndi thixotropy.Mphamvu yakunja ikagwiritsidwa ntchito, kukhuthala kwa matope kumachepa, kuwonetsetsa kuti kumagwira ntchito bwino, kupopera, ndi kupatsidwa mphamvu Pamene mphamvu yakunja imachotsedwa, kukhuthala kumawonjezeka, kotero kuti matope amakhala ndi anti-sagging komanso anti-sag performance, ndipo mu putty powder, ili ndi ubwino wowongolera kuwala kwa mafuta a putty, kuwala kowala, etc.
Zotsatira za kusunga madzi othandizira
Chifukwa cha zotsatira za gulu la hydroxypropyl mu dongosolo, wowuma ether wokha ali ndi makhalidwe a hydrophilic.Ikaphatikizidwa ndi cellulose kapena kuwonjezeredwa ku matope ena, imatha kuonjezera kusunga madzi mpaka kufika pamlingo wina ndikuwongolera nthawi yowuma pamwamba.
Anti-sag ndi anti-slip
Zabwino kwambiri zotsutsana ndi sagging, mawonekedwe ake
Redispersible latex ufa
1. Sinthani magwiridwe antchito a matope
The mphira ufa particles omwazika mu dongosolo, endowing dongosolo ndi fluidity wabwino, kuwongolera workability ndi workability wa matope.
2. Kupititsa patsogolo mphamvu ya mgwirizano ndi mgwirizano wamatope
Ufa wa rabara utamwazikana mufilimu, zinthu zakuthupi ndi zamoyo mumtondo zimasakanikirana.Zingaganizidwe kuti mchenga wa simenti mumatope ndi mafupa, ndipo ufa wa latex umapanga ligament mmenemo, zomwe zimawonjezera mgwirizano ndi mphamvu.kupanga dongosolo losinthika.
3. Limbikitsani kukana kwanyengo ndi kukana kuzizira kwamatope
Latex ufa ndi utomoni wa thermoplastic wokhala ndi kusinthasintha kwabwino, zomwe zingapangitse kuti matope azitha kupirira kuzizira kwakunja ndi kusintha kwa kutentha, komanso kuteteza bwino kuti matope asagwedezeke chifukwa cha kusintha kwa kutentha.
4. Kupititsa patsogolo mphamvu ya matope
Ubwino wa polima ndi simenti phala zimagwirizana.Pamene ming'alu imapangidwa ndi mphamvu yakunja, polima imatha kuwoloka ming'alu ndikuletsa ming'alu kuti isakule, kotero kuti kulimba kwa fracture ndi kupunduka kwa matope kumakhala bwino.
