Indima ye-p-hydroxypropyl starch ether kudaka

I-starch ether ligama eliqhelekileyo kwiklasi yesitatshi esilungisiweyo esinezibophelelo ze-ether kwi-molecule, eyaziwa ngokuba yi-starch etherified, esetyenziswa ngokubanzi kumayeza, ukutya, i-textile, i-papermaking, imichiza yemihla ngemihla, i-petroleum kunye namanye amashishini.Namhlanje sichaza ubukhulu becala indima yesitatshi ether kudaka:

1) Khubaza udaka, unyuse i-anti-sagging, anti-sagging kunye neempawu zerheological zodaka.

Umzekelo, kulwakhiwo lwe-adhesive tile, putty, kunye nodaka lokutyabeka, ngakumbi ngoku ukuba ukutshiza ngoomatshini kufuna ulwelo oluphezulu, olufana nodaka olusekwe kwigypsum, kubaluleke kakhulu (igypsum etshizwe ngomatshini ifuna ubumanzi obuphezulu kodwa iya kubangela ukudodobala okukhulu. , isitashi sikaEtere sinokwenza le ntsilelo).Oko kukuthi, xa kusetyenziswe amandla angaphandle, i-viscosity iyancipha, iphucula ukusebenza kunye nokumpompa, kwaye xa amandla angaphandle ehoxisiwe, i-viscosity iyanda, iphucula ukuchasana nokunciphisa.Kwimeko yangoku yokwandisa indawo yethayile, ukongeza isitashi se-ether kunokuphucula ukuchasana kwe-slip ye-adhesive tile.

2) Iiyure zokuvula ezongeziweyo

Ukufumana i-tile ye-tile, inokuhlangabezana neemfuno ze-adhesives ezikhethekileyo ze-tile (i-Class E, i-20min eyandisiweyo ukuya kwi-30min ukufikelela kwi-0.5MPa) eyandisa ixesha lokuvula.Isitatshi se-ether sinokwenza umphezulu wesiseko segypsum kunye nodaka lwesamente lube lula, ukulusebenzisa lula, kwaye lunesiphumo esihle sokuhombisa.Kunentsingiselo enkulu yokutyabeka udaka kunye nodaka olucekethekileyo lokuhombisa olufana ne-putty.

1. Isitashi i-ether inokuphucula ngokufanelekileyo i-anti-sag kunye ne-anti-slip properties of mortar

I-Cellulose ether ngokuqhelekileyo inokuphucula kuphela i-viscosity kunye nokugcinwa kwamanzi kwenkqubo kodwa ayikwazi ukuphucula iimpawu ezichasayo kunye ne-anti-slip.

2. Ukutyeba kunye ne-viscosity

Ngokuqhelekileyo, i-viscosity ye-cellulose ether imalunga namashumi amawaka, ngelixa i-viscosity ye-starch ether ingamakhulu aliqela ukuya kumawaka aliqela, kodwa oku akuthethi ukuba ukujiya kwepropathi ye-starch ether ukuya kudaka ayilunganga njengaleyo ye-cellulose ether, kwaye indlela yokujiya kwezi zibini zahlukile.

3. Ukusebenza kwe-Anti-slip

Xa kuthelekiswa ne-cellulose ethers, i-starch ethers inokunyusa kakhulu ixabiso lesivuno sokuqala se-adhesive tile, ngaloo ndlela iphucula iimpawu zabo zokuchasana.

4. Ukungenisa umoya

I-ether ye-cellulose inepropati eyomeleleyo yokungenisa umoya, ngelixa i-starch ether ingenayo ipropati yokungenisa umoya.
