Impembelelo ye-cellulose ether kwi-putty powder

1. i-ether cellulose - i-ether ye-cellulose eyandulelayo

I-cellulose ether yeyona polysaccharide ixhaphakileyo kwihlabathi namhlanje.Imithombo ephambili ye-cellulose yendalo yikotoni, imithi, izityalo zasemanzini, ingca kunye nokunye.Umqhaphu uqulethe i-92-95% ye-cellulose;I-Flax iqulethe malunga ne-80% ye-cellulose;Imithi iqulethe malunga ne-50% ye-cellulose.

2, isakhiwo se-ether cellulose

I-cellulose ether i-polysaccharide eyinkimbinkimbi equkethe amawaka eeyunithi ze-glucose kwi-molecule, i-chemical formula (C6H10O5) N. Iqela le-D-glucose liboshwe yi-β - 1,4 glucoside bonds.

Iingxaki eziqhelekileyo kunye nezizathu eziphambili zokumelana kwamanzi putty eludongeni lwangaphakathi

Iindlela eziqhelekileyo zokusombulula iingxaki

Iputty engathathi hlangothi:

I-Depowder: i-cementitious material eyaneleyo, i-cellulose ether ukugcinwa kwamanzi ayanele, umxholo we-calcium we-calcium enzima uphantsi.

Ukusebenza kokwakhiwa: kuphuculwe yi-bentonite kunye ne-starch ether.

Igubu elingenanto;Kwaye ukunamathela eludongeni okubangelwa ukungonelanga.

Ulwaleko: ukusetyenzwa kojongano.

Amandla: Inokulungiswa kwakhona ngokubeka i-calcium powder.

Ikalika ye-calcium putty:

Iingxaki zigubu ezingenanto, i-depowder yellowing, ukwakhiwa akulungile, i-depowder, i-stratification, i-crack, emva kokuqina;

I-Depowder: i-cementitious material eyaneleyo, i-cellulose enganeleyo yokugcina amanzi okanye inani elaneleyo lokongezwa, i-lime calcium ayihlambulukanga.

Ukusebenza kakubi kokwakhiwa: i-bentonite kunye ne-starch ether ukuphucula.

Igubu elingenanto;Kwaye ukunamathela eludongeni okunganeleyo okubangelwa ukongezwa okufanelekileyo kwe-latex powder.

Ulwaleko: ukusetyenzwa kojongano.

Mthubi: ukhetho olungafanelekanga lwe-cellulose ether.

Ukuqhekeka: Ukuqhekeka kwesiseko okanye ukomelela okuqhekeka kakhulu, ukugquma kakhulu.

Emva kokuqina: izinga lokufunxa amanzi e-calcium elinzima lihlukile, kuyacetyiswa ukuba ukhethe ukufunxa kwamanzi angama-zero okanye umgubo ophantsi kakhulu we-calcium;I-calcium engwevu iqulethe i-GaO engagatywanga.

Iputty esekwe kwisamente:

Iingxaki zomgqomo ongenanto, ukwakhiwa akulungile, i-depowder, i-delamination, i-cracking, ukuchasana kwamanzi okwaneleyo, i-coagulation yobuxoki;

I-Depowder: I-depowder: imathiriyeli yesamente eyanelanga, i-cellulose ether enganelanga yokugcina amanzi okanye isixa esinganelanga sokongeza.

Ukusebenza kakubi kokwakhiwa: i-bentonite kunye ne-starch ether ukuphucula.

Igubu elingenanto: kunye nokunamathela eludongeni okubangelwa ukungonelanga, ukongezwa okufanelekileyo kwe-latex powder.

Ulwaleko: ukusetyenzwa kojongano.

Mthubi: Ukukhetha okungafanelekanga kweselulosi.

Ukunganyangeki kwamanzi: ukungonelanga kwe-latex powder kunye nezixhobo ze-cementitious ezinganeleyo.

Ukuqhekeka: ukuqhekeka kwesiseko okanye ukomelela okuphezulu kakhulu, ukugquma kukhulu kakhulu, kunye ne-putty yokugcwalisa umngxuma.

I-coagulation yobuxoki: i-sodium gluconate inokongezwa ukwandisa ixesha lokusebenza.
