CAS:9004-65-3
IHydroxypropyl Methyl Cellulose (HPMC) ikwabizwa ngokuba yi-MHPC, luhlobo lwe-non-ionic cellulose ether, engumgubo omhlophe ukuya kumbala omhlophe, osebenza njenge-thickener, binder, ifilimu-yangaphambili, i-surfactant, i-colloid ekhuselayo, i-lubricant, i-emulsifier, kunye ne-suspension kunye noncedo lokugcina amanzi. Ukongeza, ezi ntlobo ze-cellulose ethers zibonisa iipropathi ze-thermal gelation, inertness ye-metabolic, ukumelana ne-enzyme, ivumba eliphantsi kunye nencasa, kunye nokuzinza kwe-pH. HPMC zisetyenziswa ngokubanzi kulwakhiwo, amayeza, ukutya, izithambiso, isepha, iipeyinti, iingubo etc.Sinokubonelela ibakala jikelele HPMC, siye sayila HPMC modified ngokweemfuno zabathengi. Emva kokuguqulwa, sinokufumana imveliso enexesha elide elivulekileyo, i-anti-sagging elungileyo, ukusebenza kakuhle njl.

Usetyenziso:
Iputty eludongeni
- Ukugcinwa kwamanzi: Ukwandisa umthamo wamanzi eludaka.
- I-Anti-sagging: xa usasaza i-corrugation yedyasi engqindilili inokuthintelwa.
- Ukonyuka kwesivuno sodaka: ngokuxhomekeke kubunzima bomxube owomileyo kunye nokwakheka okufanelekileyo, i-HPMC inokunyusa umthamo wodaka.
I-Insulation yangaphandle kunye neNkqubo yokuGqibela ( EIFS )
- Ukuphucula ukunamathela.
- Isakhono esihle sokumanzisa kwibhodi ye-EPS kunye ne-substrate.
- Ukuncitshiswa kokungena komoya kunye nokuthathwa kwamanzi.
Ukuzilinganisa
Ukukhuselwa ekukhutshweni kwamanzi kunye ne-sedimentation yezinto eziphathekayo.
Akukho mpembelelo kwi-slurry fluidity ene-viscosity ephantsi
I-HPMC, ngelixa iimpawu zayo zokugcina amanzi ziphucula ukusebenza kokugqiba kumphezulu.
I-Crack Filler
Ukusebenza ngcono: ubukhulu obufanelekileyo kunye neplastiki.
Ukugcinwa kwamanzi kuqinisekisa ixesha elide lomsebenzi.
Ukuxhathisa kwe-Sag: ubuchule obuphuculweyo bokudibanisa udaka.
Izincamathelisi zeThayile
Ukusebenza okungcono: i-lubricity kunye ne-plasticity ye-plaster iqinisekisiwe, udaka lunokufakwa lula kwaye lukhawuleza.
Ukugcinwa kakuhle kwamanzi: ixesha elide lokuvula liya kwenza ukuba iithayile zisebenze kakuhle.
Ukubambelela okuphuculweyo kunye nokumelana nokutyibilika: ngakumbi kwiithayile ezinzima.
Udaka lomxube owomileyo
Ifomula yokuxuba eyomileyo ngokulula ngenxa yokunyibilika kwamanzi abandayo: ukubunjwa kweqhuma kunokuphetshwa ngokulula, ilungele iithayile ezinzima.
Ukugcinwa kwamanzi okulungileyo: ukukhuselwa kokulahleka kwamanzi kwii-substrates, umxholo wamanzi ofanelekileyo ugcinwa kumxube oqinisekisa ixesha elide lokudibanisa.
iPlaster yesamente
Ukonyuka kwemfuno yamanzi: ixesha elongeziweyo elivulekileyo, indawo eyandisiweyo yespry kunye nokwakhiwa okunoqoqosho ngakumbi.
Ukusasazeka lula kunye nokuphucula ukuxhathisa ukudodobala ngenxa yokuphucula ukungaguquguquki.
Ukupakishwa:
IMveliso ye-HPMC ipakishwe kwingxowa yephepha yomaleko emithathu kunye nengxowa ye-polyethylene yangaphakathi eqinisiwe, ubunzima bobunzima bungama-25kg ingxowa nganye.
Ugcino:
Yigcine kwindawo epholileyo eyomileyo, kude nokufuma, ilanga, umlilo, imvula.
Ixesha lokuposa: May-19-2021
