Lub hauv paus ntsiab lus ntawm cov hnab ntim khoom siv nqus tsev, ntxiv rau kev tiv thaiv cov kab mob me me kom tsis txhob loj hlob thiab sib kis hauv, kuj tseem siv los tiv thaiv kev oxidation ntawm cov khoom noj.
Cov hnab ntim khoom siv nqus tsev yog muab faib ua cov hnab ntim khoom khov thiab cov hnab ua noj. Cov hnab ntim khoom khov siv nqus tsev yog siv dav, xws li: cov noob txiv ntoo walnut, nqaij nyuj, nqaij yaj, pob mov, dumplings thiab lwm yam. Peb tuaj yeem pom cov no txhua qhov chaw hauv cov khw muag khoom loj. Hauv lub neej, ntau thiab ntau cov khoom noj khov xaiv cov hnab ntim khoom siv nqus tsev, lub hom phiaj tseem ceeb yog kom zoo thiab tshiab.
Cov hnab ntim khoom noj khov uas muaj lub tshuab nqus tsev khov muaj cov yam ntxwv tiv taus kev cuam tshuam zoo, suav nrog lub zog tensile thiab elongation thaum tawg, uas qhia txog lub peev xwm ntawm cov khoom kom tiv taus kev ncab thaum siv. Yog tias cov khoom no tsis tsim nyog, thaum siv cov hnab ntim khoom noj yuav tawg thiab puas tsuaj. Tom qab cov khoom noj khov raug ntim hauv lub tshuab nqus tsev, nws yuav tsum tau thauj, thauj khoom thiab tshem tawm, muab tso rau ntawm txee, thiab lwm yam. Thaum lub sijhawm no, lub hnab nqus tsev khov khoom noj khov yooj yim puas tsuaj los ntawm cov zog sab nraud. Yog tias lub hnab ntim khoom noj khov uas muaj lub tshuab nqus tsev tsis zoo, nws yooj yim heev rau kev tawg lub hnab thiab qhib lub hnab. , tsis tsuas yog cuam tshuam rau qhov zoo li ntawm cov khoom ntim, tab sis kuj tsis tuaj yeem ua lub luag haujlwm ntawm cov ntim khoom nws tus kheej.
Ntxiv rau, nws kuj suav nrog cov cim qhia txog kev thaiv roj xws li roj permeability; cov cim qhia txog kev tiv thaiv roj, kev tiv thaiv kub, kev tiv thaiv txias, kev tiv thaiv nruab nrab; lub hnab kaw thiab lub zog tev tawv, lub hnab tiv thaiv siab thiab kev tiv thaiv poob thiab lwm yam cim qhia, cov cim qhia no qhia txog lub hnab ntim khoom noj. Kev ntseeg siab ntawm kev tiv thaiv sab hauv.
Zoo ductility, tear resistant, tsis yooj yim rau tawg
Cov hnab kaw cua sov peb sab yog qhov tsim nyog rau feem ntau cov tshuab kaw cua sov
Txhua yam khoom raug kuaj xyuas nrog lub chaw kuaj xyuas QA zoo tshaj plaws thiab tau txais daim ntawv pov thawj patent.
