I-Hydroxyethyl Methyl Cellulose (HEMC)

IHydroxyethyl methyl cellulose (HEMC) yipolima enyibilikayo emanzini ephuma kwiselulosi. Yiyo i-ionic, i-non-toxic, kunye ne-non-flammble compound esetyenziswa ngokubanzi kwi-industry-industry kunye nezicelo zabathengi. I-HEMC ixabiswa ngenxa yokukwazi ukusebenza njenge-thickener, binder, kunye ne-rheology modifier kwiimveliso ezininzi.

I-HEMC yenziwa ngokuguqula imicu yendalo ye-cellulose ngokwemichiza. Kule nkqubo, i-cellulose fibers iphathwa nge-sodium hydroxide ukwenza i-alkali cellulose. I-ethylene oxide iye yongezwa kumxube, edibana neselulosi ukwenza i-hydroxyethyl cellulose. Ekugqibeleni, i-methyl chloride yongezwa kumxube ukudala i-HEMC.

I-HEMC isetyenziswa kuluhlu olubanzi lwezicelo, kubandakanya ukwakhiwa, ukutya, ukhathalelo lomntu, kunye namayeza. Olunye lolona setyenziso luphambili lwe-HEMC kulwakhiwo, apho isetyenziswa kwiimveliso ezahlukeneyo ezinje ngodaka lomxube owomileyo, iiputty, izinto zokuncamathelisa iithayile, kunye neemveliso zegypsum.

Kwimibhobho yomxube owomileyo, i-HEMC isetyenziswa njenge-thickener, i-binder, kunye ne-arhente yokugcina amanzi. Inceda ukuphucula ukusebenza kodaka kwaye ivumela ulawulo olungcono lomxholo wamanzi. Oku kubalulekile kuba umxholo wamanzi wodaka uchaphazela ukuhambelana kwawo, ixesha lokubeka, kunye namandla okugqibela.

Kwi-putty, i-HEMC isetyenziswa ngokuyintloko njenge-thickener kunye ne-binder. Ukongezwa kwe-HEMC kumxube kunceda ukuphucula ukusebenza kwe-putty kwaye ivumela ukulawula okungcono komxholo wamanzi. I-HEMC iphinda incede ukuthintela ukuhlukana kwamacandelo ahlukeneyo kwi-putty formulation, kwaye iphucula ukunamathela kwe-putty kwi-substrates.

Kwii-adhesives ze-tile, i-HEMC isetyenziswe ngokuyinhloko njenge-arhente yokugcina amanzi. Ukongezwa kwe-HEMC kumxube kunceda ukuphucula ukusebenza kwe-adhesive kwaye ivumela ukulawula okungcono komxholo wamanzi. I-HEMC iphinda incede ukuthintela ukuhlukana kwamacandelo ahlukeneyo ekubunjweni kwe-adhesive, kwaye iphucula ukunamathela kwe-adhesive kwi-substrates.

Kwiimveliso ze-gypsum, i-HEMC isetyenziswa njenge-thickener, i-binder, kunye ne-arhente yokugcina amanzi. Inceda ukuphucula ukusebenza kwemveliso ye-gypsum kwaye ivumela ukulawulwa okungcono komxholo wamanzi. Oku kubalulekile kuba umxholo wamanzi wemveliso ye-gypsum uchaphazela ixesha layo lokumisela kunye namandla okugqibela.

Kwiimveliso zokutya, i-HEMC isetyenziswa ngokuqhelekileyo njenge-thickener, stabilizer, kunye ne-emulsifier. Isetyenziswa kwiintlobo ezininzi zeemveliso zokutya, kubandakanywa iisosi, izinxibo kunye neemveliso zobisi. I-HEMC ixabiswa ngokukwazi kwayo ukuphucula ukuthungwa kunye nokuzinza kwezi mveliso.

Kwiimveliso zokhathalelo lomntu, i-HEMC isetyenziswa njenge-thickener, stabilizer, kunye ne-emulsifier. Isetyenziswa kwiintlobo ezininzi ezahlukeneyo zeemveliso zokhathalelo lomntu, kubandakanya ishampu, iiconditioners, kunye neloshini. I-HEMC ixabiswa ngokukwazi kwayo ukuphucula ukuthungwa kunye nokuzinza kwezi mveliso.

Kwimichiza, i-HEMC isetyenziswa njenge-binder kunye ne-disintegrant. Isetyenziselwa ukuqulunqwa kwethebhulethi ukuphucula amandla omatshini wethebhulethi kunye nokunceda ukuchithwa kwethebhulethi kunye nokutshatyalaliswa komzimba.
