Pregelatinized Cassava Starch tsis yog tawg -inducing raw khoom. Thaum siv nrog cov txheej txheem txheej txheem thiab cov khoom siv muaj txiaj ntsig, nws ua kom muaj kev ncaj ncees, yoog raws thiab tawg tsis kam ntawm cov khoom tiav. Cov teeb meem tawg tsuas yog tshwm sim nyob rau hauv cov ntawv thov txawv txav xws li kev sib ntxiv ntau dhau, tsis sib npaug ntawm qhov sib npaug thiab tsis yog- tus qauv ua, ib qho kev xav tsis zoo hauv cov ntawv thov kev lag luam. Cov laj thawj tseem ceeb ntawm cov khoom tawg yog suav nrog qhov tsis sib xws curing shrinkage, ntau sab hauv cov dej tsis zoo, siab brittleness ntawm cov nplaum nplaum, cov kev ntxhov siab sab hauv thiab tsis txaus tsim thiab kho. Daim ntawv thov txheej txheem ntawm Pregelatinized Cassava Starch tuaj yeem txo qhov tsis zoo no.
Cov yeeb yaj kiab colloidal tsim los ntawm gelatinized Pregelatinized Cassava Starch muab kev yooj yim thiab ductility, sib txawv ntawm cov yam ntxwv ntawm cov tawv tawv thiab tawv tawv. Hauv cov txheej txheem xws li qhuav-sib tov mortar, ceramic ntsuab lub cev, pub pellets thiab nias cov khoom, nws uniformly qhwv cov ntaub ntawv hais, txhim kho lub zuag qhia tag nrho kev sib cog lus compactness ntawm cov ntaub ntawv, buffers shrinkage kev nyuaj siab thaum kho, ziab thiab tu, thiab txo cov kev pheej hmoo ntawm qhuav -shrinkage cracking thiab kub - sib txawv. Nws lub peev xwm khaws dej nruab nrab qeeb qeeb hauv cov dej noo volatilization hauv cov khoom tiav, tiv thaiv cov kab nrib pleb qhuav thiab cov kab nrib pleb sab hauv uas tshwm sim los ntawm kev ya raws sai, thiab txhim kho txoj kev ruaj ntseg ntawm cov khoom kawg.
Cov khoom tawg yog tshwj xeeb vim yog kev siv tsis raug. Ua ntej, kev sib ntxiv ntau dhau ua rau ntau tshaj - feem ntau ntawm cov hmoov txhuv nplej siab hauv lub cev thiab dilutes inorganic muab tub lim. Lub curing thiab drying shrinkage coefficient ntawm cov hmoov txhuv nplej siab yog siab dua li ntawm cov khoom siv inorganic, ua rau muaj kev nce zuj zus ntawm cov khoom tiav thiab tsis sib xws hauv kev ntxhov siab, uas nws thiaj li ua rau deg microcracks, ntug fractures thiab tag nrho crazing. Qhov thib ob, qhov sib npaug ntawm cov mis tsis sib npaug tsis tuaj yeem kho cov yam ntxwv ntawm lub ntsws los ntawm kev sib sau ua ke thiab cov fillers, thiab tshaj - kev cia siab rau cov hmoov txhuv nplej siab ua kom muaj qhov cuam tshuam ntawm qhov tsis xws luag.
Tsis tas li ntawd, kev tsim kho tsis tsim nyog thiab kev kho cov txheej txheem ua rau muaj kev cuam tshuam ntau ntxiv. Siab - kub ceev kom qhuav, cua ntau dhau thiab lub sij hawm kho tsis txaus tom qab tsim tuaj yeem ua rau tawg vim tias ya raws sai sai, txawm tias muaj cov hmoov txhuv nplej siab. Kev lag luam - tus qauv ntau npaum li cas ntawm Pregelatinized Cassava Starch yog li ntawm 1% mus rau 6%, nrog rau kev hloov me me raws li cov khoom lag luam, ua tiav cov khoom siv tau yooj yim, compactness thiab tawg tsis kam. Kev tswj kev noj tshuaj nruj me ntsis thiab kho cov txheej txheem kho kom zoo kom tshem tawm cov kev pheej hmoo ntawm kev tawg, thaum qhov muag tsis pom - ntxiv rau qhov tseem ceeb ntawm tib neeg -vim ua rau cov khoom tiav tawg.
