Kugwiritsa Ntchito Hydroxypropyl Methylcellulose (HPMC)

Hydroxypropyl methylcellulosendi wamba zopangira mu zomangira mankhwala makampani.Pakupanga tsiku ndi tsiku, nthawi zambiri timatha kumva dzina lake.Koma anthu ambiri sadziwa ntchito yake.Lero, ndikufotokozerani kugwiritsa ntchito hydroxypropyl methylcellulose m'malo osiyanasiyana.

1. Mtondo womangira, pulasitala matope

Monga chosungira madzi ndikubwezeretsanso matope a simenti, imatha kupititsa patsogolo kutulutsa kwamatope, kupititsa patsogolo kufalikira ndikutalikitsa nthawi yogwira ntchito.Kusungidwa kwa madzi kwa HPMC kumatha kuletsa slurry kuti isaphwanyike chifukwa chowuma mwachangu mukatha kugwiritsa ntchito, ndikuwonjezera mphamvu mukaumitsa.

2. Putty wosamva madzi

Mu putty, cellulose ether makamaka imagwira ntchito yosungira madzi, kugwirizana ndi kuyamwitsa, kupewa ming'alu ndi kutaya madzi m'thupi chifukwa cha kutaya madzi ambiri, komanso kupititsa patsogolo kumamatira kwa putty, kuchepetsa zochitika za kugwedezeka panthawi yomanga, kupanga. ntchito yomanga bwino.

3. Pulasita pulasitala

Mu mankhwala gypsum mndandanda, mapadi etero makamaka amasewera ntchito posungira madzi, thickening ndi kondomu, ndipo ali ndi zotsatira zina retarding pa nthawi yomweyo, amene amathetsa vuto la unfikiable mphamvu koyamba pa ntchito yomanga, ndipo akhoza kutalikitsa nthawi ntchito.

4. Interface wothandizira

Imagwiritsidwa ntchito makamaka ngati thickener, imatha kupititsa patsogolo kulimba kwamphamvu komanso kumeta ubweya, kukonza zokutira pamwamba, kukulitsa kumamatira ndi mphamvu zamagwirizano.

5. Mtondo wotsekera kunja kwa makoma akunja

Cellulose ether makamaka imagwira ntchito yolumikizana ndikuwonjezera mphamvu pazinthu izi.Ndikosavuta kuvala mchenga, kukonza magwiridwe antchito, ndipo kumakhala ndi zotsatira za anti-sag flow.Kuchita kwapamwamba kosungirako madzi kumatha kutalikitsa nthawi yogwira ntchito yamatope ndikuwongolera kukana Shrinkage ndi kukana ming'alu, kukhathamiritsa kwapamwamba, kuwonjezereka kwamphamvu kwa mgwirizano.

6, caulking wothandizira, dzenje olowa wothandizira

Kuwonjezera pa cellulose ether kumapereka zabwino m'mphepete adhesion, otsika shrinkage ndi mkulu abrasion kukana, amene amateteza zinthu m'munsi ku kuwonongeka makina ndi kupewa zotsatira za malowedwe pa nyumba yonse.

7. DC lathyathyathya zakuthupi

Kugwirizana kokhazikika kwa cellulose ether kumatsimikizira kusungunuka kwamadzi komanso kudziwongolera, ndikuwongolera kuchuluka kwa madzi osungirako kuti athe kulimba mwachangu ndikuchepetsa kusweka ndi kuchepa.

8. utoto wa latex

M'makampani okutira, ma cellulose ethers angagwiritsidwe ntchito ngati oyambitsa filimu, thickeners, emulsifiers ndi stabilizers, kotero kuti filimuyo imakhala ndi kukana kwabwino kwa abrasion, kusanja, kumamatira, ndi PH zomwe zimapangitsa kuti kugwedezeka kwapamwamba ndikwabwino , The miscibility ndi zosungunulira organic ndi zabwino. , komanso kusungirako madzi kwapamwamba kumapangitsa kuti ikhale ndi brushability yabwino komanso mitsinje yoyenda bwino.

Ndikukhulupirira kuti aliyense amadziwa za hydroxypropyl methylcellulose.Monga zopangira zofunikira pamakampani opanga mankhwala, hydroxypropyl methylcellulose imakhudza mtundu wazinthu zakutsika.Chifukwa chake, posankha hydroxypropyl methylcellulose, onetsetsani kuti mwatsegula maso anu.Zida zapamwamba zokha zimatha kupanga zinthu zapamwamba kwambiri.
