Hangzhou Rainbow Ntshuam & Export Co., Ltd. yog ib qho ntawm cov ua lag luam thiab cov muag khoom ntawm Povidone K25 hauv Suav teb. Nrog kev paub ntau ntxiv, peb zoo siab tos txais koj los yuav customized Povidone K25 los ntawm peb lub hoobkas. Yog tias koj muaj lus nug txog cov qauv dawb, thov koj xav email rau peb.
Cov khoom qib tshwj xeeb ntawm polyvinylpyrrolidone (PVP), "K25", sawv cev rau qhov nruab nrab ntawm cov txheej txheem polymerization thiab cov khoom siv tshuaj. Nws yog polymerized los ntawm N-vinylpyrrolidone monomers.
Lub cev thiab tshuaj muaj zog
Solubility: Nws muaj cov dej solubility zoo heev los tsim cov kua dej ntshiab, pob tshab thiab ruaj khov. Nws kuj muaj zoo solubility nyob rau hauv polar organic solvents xws li ethanol, uas ua rau nws saj zawg zog nyob rau hauv txawv formulation systems.
Viscosity zog: "K tus nqi" ntawm K25 txiav txim siab nws cov viscosity kev ua tau zoo hauv kev daws. Qhov nruab nrab ntawm polymerization muab nws cov tshuaj aqueous ib nrab viscosity, uas plays lub luag haujlwm tseem ceeb hauv ntau daim ntawv thov scenarios uas yuav tsum tau tswj cov kua dej. Piv txwv li, thaum nws yaj nyob rau hauv dej los tsim ib qho kev daws teeb meem ntawm ib tug tej yam concentration, cov tshuaj yuav tsis heev nyias kom poob lub peev xwm mus disperse thiab stabilize lwm yam khoom xyaw, los yog nws yuav viscous heev rau kev ua thiab siv.
Chemical stability: Nws tuaj yeem nyob ruaj khov nyob rau hauv ntau qhov pH (ruaj khov nyob rau hauv pH 3.0-7.0) thiab tsis muaj tshuaj lom neeg xws li hydrolysis thiab oxidation. Qhov no tso cai rau nws siv nrog ntau yam acidic, alkaline lossis nruab nrab yam tsis muaj kev cuam tshuam rau nws tus kheej kev ua tau zoo lossis cuam tshuam nrog lwm cov khoom xyaw vim kev hloov pauv hauv cov tshuaj ib puag ncig.
Koj ua li cas kom ntseeg tau qhov zoo ntawm koj cov Povidone K25?
Peb siv cov thev naus laus zis siab thiab ruaj khov polymerization tshuab, thiab cov txheej txheem tsim khoom nruj me ntsis ua raws li ISO 9001 cov txheej txheem zoo. Los ntawm kev yuav khoom thiab tshuaj xyuas cov ntaub ntawv raw N-vinyl pyrrolidone, mus rau qhov kev tswj hwm ntawm qhov tsis xws li qhov kub, siab, thiab cov tshuaj pib siv rau hauv cov tshuaj tiv thaiv, mus rau ntau- cov txheej txheem kuaj cov khoom tiav, suav nrog kev txiav txim siab cov ntsiab lus, tsis pom kev tsis pom kev, kev tshuaj xyuas microbial txwv, thiab lwm yam. yuav muab nrog cov khoom.
Piv nrog rau lwm cov tuam ntxhab, qhov twg yog tus nqi kom zoo dua?
Peb muaj - nplai ntau lawm hauv paus. Los ntawm kev ua kom zoo ntawm kev tswj cov saw hlau thiab kev koom tes ncaj qha nrog siab -cov khoom siv raw khoom zoo, tus nqi ntawm cov khoom siv raw khoom tau raug txo. Nyob rau tib lub sijhawm, peb txuas ntxiv txhim kho cov txheej txheem tsim khoom, txhim kho kev tsim khoom, thiab txo qis kev siv hluav taws xob thiab kev poob. Hauv cov ntsiab lus, peb tus nqi K 25 yog 10% - 15% qis dua cov khoom zoo sib xws ntawm kev ua lag luam nyob rau nruab nrab, tab sis cov khoom zoo yog ua raws li tag nrho los yog siab dua li cov qauv kev lag luam.
Lub voj voog xa khoom thiab qhov kev txiav txim yam tsawg kawg nkaus yog dab tsi?
Rau kev txiav txim tsis tu ncua, peb lub voj voog xa khoom yog 3-5 hnub ua haujlwm; yog tias nws yog qhov kev txiav txim loj lossis loj, peb yuav sib tham nrog koj raws li qhov xwm txheej tiag tiag, feem ntau tsis pub dhau 10 hnub ua haujlwm. Yam tsawg kawg nkaus kom muaj nuj nqis yog hloov tau yooj yim. Thawj qhov kev koom tes txhawb nqa me me batch mus sib hais. Hauv kev koom tes tom qab, raws li qhov ntim yuav nce ntxiv, peb tseem yuav muab cov nqi txo nqi ntau dua thiab cov nqi them rov qab.
Povidone K25 muaj kev txhawb nqa dab tsi hauv cov ntawv thov sib txawv?
Peb tau nruab nrog ib pab neeg ua haujlwm tshaj lij los muab tag nrho -kev txhawb nqa rau ntau yam kev thov xws li tshuaj, tshuaj pleev ib ce, thiab zaub mov. Piv txwv li, nyob rau hauv txoj kev loj hlob ntawm kev npaj tshuaj, peb pab nyob rau hauv optimizing cov mis nyuj thiab daws tej teeb meem xws li adhesion, solubilization, thiab sustained tso; nyob rau hauv daim ntawv thov ntawm cov tshuaj pleev ib ce, peb muab cov lus qhia thiab cov kev daws teeb meem ntawm cov khoom viscosity hloov thiab zaj duab xis- tsim kev ua tau zoo. Tsuav koj muaj kev xav tau, koj tuaj yeem tiv tauj peb cov kws tshaj lij txhua lub sijhawm, thiab peb yuav teb tsis pub dhau 24 teev.
Kuv yuav tsum xyuam xim rau dab tsi hauv kev khaws cia thiab kev thauj mus los ntawm cov khoom?
Thaum lub sij hawm kev thauj mus los, peb siv cov dej noo- pov thawj thiab ntim ntim kom ntseeg tau tias cov khoom tsis ntub los yog paug. Rau kev khaws cia, nws raug nquahu kom khaws cov khoom nyob rau hauv qhov chaw txias, qhuav, ventilated warehouse nrog qhov kub ntawm 0 - 30℃thiab ib tug txheeb ze av noo ntawm tsis ntau tshaj 65%. Nyob rau hauv xws li kev cia khoom, cov khoom txee lub neej yog 2 xyoos. Peb kuj tseem yuav qhia meej meej txog kev khaws cia thiab kev thauj mus los ceev faj ntawm cov khoom ntim khoom.
