Izinto eziluncedo zeHPMC&MHEC kwiimveliso zodaka olomileyo oluxutyiweyo

Intshayelelo kwi-HPMC kunye ne-MHEC:

I-HPMC kunye ne-MHEC zi-ether ze-cellulose ezisetyenziswa ngokuqhelekileyo kwizinto zokwakha, kubandakanywa nodaka oluxubeneyo olumileyo. Ezi polymers zithathwe kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zezityalo. Xa zongezwa kwimixube eyomileyo, i-HPMC kunye ne-MHEC zisebenza njengama-thickeners, ii-agent ezigcina amanzi, i-binders, kunye nokuphucula ukusebenza kunye neepropati zokubambisana.

1. Ukugcinwa kwamanzi:

I-HPMC kunye ne-MHEC zi-polymers ze-hydrophilic, oku kuthetha ukuba banobudlelwane obuphezulu bamanzi. Xa zifakwe kwimibhobho yomxube owomileyo, zenza ifilimu encinci phezu kweengqungquthela zesamente, ukuthintela ukukhuphuka kwamanzi ngokukhawuleza ngexesha lokunyanga. Le hydration ixesha elide kwandisa amandla uphuhliso lodaka, kunciphisa umngcipheko wokuqhekeka kunye nokuqinisekisa ukusetwa okuchanekileyo.

2. Phucula ukusebenza:

I-HPMC kunye ne-MHEC ziphucula ukusebenza kodaka lomxube owomileyo ngokunika i-lubrication. Basebenza njengeplastiki, ukunciphisa ukungqubuzana phakathi kwamasuntswana kunye nokwenza udaka lube lula ukuxuba, ukusabalalisa nokugqiba. Oku kuphucuka kokusebenza kubangela ukuhambelana okungcono kunye nokufana komgangatho wodaka olusetyenzisiweyo.

3. Yandisa iiyure zokuvula:

Ixesha elivuliweyo lixesha apho udaka luhlala lusetyenziswa emva kokuxuba. I-HPMC kunye ne-MHEC zandisa ixesha elivulekileyo lodaka lomxube owomileyo ngokunciphisa izinga lokuphuma kwamanzi. Olu phawu luluncedo ngokukhethekileyo kwiiprojekthi ezinkulu zokwakha ezifuna ixesha elongeziweyo lomsebenzi, njengeethayile okanye udaka lwezicelo.

4. Nyusa ukuncamathela:

Ubukho be-HPMC kunye ne-MHEC kwimibhobho yokuxuba eyomileyo ikhuthaza ukunamathela okungcono kwiintlobo ze-substrates ezibandakanya ikhonkrithi, i-masonry kunye neetayile ze-ceramic. Ezi polymers zenza ubumbano phakathi kodaka kunye ne-substrate, ukuphucula ukuqina kunye nokusebenza kwezinto ezisetyenzisiweyo. Ukongeza, banciphisa umngcipheko wokwahlula kunye nokwahlula ixesha.

5. Ukumelana neecrack:

Ukuqhekeka yingxaki eqhelekileyo ngodaka, ngakumbi ngexesha lokumisa kunye nenqanaba lokunyanga. I-HPMC kunye ne-MHEC inceda ukunciphisa le ngxaki ngokuphucula ukudibanisa kunye nokuguquguquka kwe-matrix yodaka. Ngokunciphisa ukucutheka kunye nokulawula inkqubo yokufakwa kwamanzi, ezi polymers zinceda ekuphuculeni ukuxhathisa kokuqhekeka kodaka olugqityiweyo, okukhokelela kulwakhiwo oluhlala ixesha elide.

6. Ukuguquguquka:

I-HPMC kunye ne-MHEC zizongezo eziguquguqukayo ezinokuthi zisetyenziswe kwiindidi ezahlukeneyo zomxube owomileyo wodaka. Ingaba i-masonry mortars, i-adhesives ye-tile, i-self-leveling compounds okanye ukulungiswa kwee-polymers, ezi zi-polymers zibonelela ngokusebenza okuhambelanayo kunye nokuhambelana nezinye izithako. Oku kuguquguquka kwenza lula inkqubo yokuvelisa kwaye ivumela uphuhliso lwezisombululo zodaka lwesiko kwizicelo ezithile.

7. Iinzuzo zokusingqongileyo:

I-HPMC kunye ne-MHEC zizongezo ezihambelana nokusingqongileyo ezivela kwimithombo evuselelekayo. Ukusetyenziswa kwabo kwimibhobho yomxube owomileyo kunceda ukunciphisa ukusetyenziswa kwemithombo yendalo kunye nokunciphisa ukuveliswa kwenkunkuma, ngaloo ndlela kukhuthazwa uphuhliso oluzinzileyo. Ukongeza, ukonakaliswa kwebhayoloji kuqinisekisa impembelelo encinci yokusingqongileyo ekupheleni komjikelo wobomi bodaka.

I-HPMC kunye ne-MHEC zineenzuzo ezininzi kwaye ezibalulekileyo kwiimveliso zodaka ezinomxube owomileyo. Ukusuka ekuphuculeni ukusebenza kunye nokubambelela ekwandiseni ukuchasana nokuqhekeka kunye nokuqina, ezi ether ze-cellulose zidlala indima ebalulekileyo ekuphuculeni ukusebenza kunye nobude obude bodaka kwizicelo zokwakha. Njengezongezo ezizinzileyo neziguquguqukayo, i-HPMC kunye ne-MHEC zihlala zilukhetho lokuqala kubavelisi abajonge ukukhulisa ukusebenza kodaka lwabo lodaka ngelixa benciphisa impembelelo yokusingqongileyo.
