Zodzikongoletsera thickeners ndi stabilizers

01 Wonenepa

thickener:Pambuyo kusungunuka kapena omwazika m'madzi, akhoza kuonjezera mamasukidwe akayendedwe a madzi ndi kukhala ndi khola hydrophilic polima pawiri mu dongosolo. Mapangidwe a maselo ali ndi magulu ambiri a hydrophilic, monga -0H, -NH2, -C00H, -COO, ndi zina zotero, zomwe zimatha kuthira madzi ndi mamolekyu amadzi kuti apange yankho la macromolecular high-viscosity. Thickeners amagwira ntchito yofunika kwambiri mu zodzoladzola , ndi thickening, emulsifying, suspending, stabilizing ndi ntchito zina.

02 Thickener action Mfundo

Popeza magulu ogwira ntchito pa unyolo wa polima nthawi zambiri sakhala amodzi, njira yokhuthala nthawi zambiri imakhala kuti chokhuthala chimodzi chimakhala ndi njira zingapo zokhuthala.

Kukhuthala kwa unyolo: Polima atayikidwa mu zosungunulira, maunyolo a polima amapindika ndikumangana wina ndi mnzake. Panthawi imeneyi, kukhuthala kwa yankho kumawonjezeka. Pambuyo neutralization ndi alkali kapena organic amine, mlandu zoipa ali amphamvu solubility madzi, zimene zimapangitsa unyolo polima mosavuta kuwonjezera, potero kukwaniritsa kuwonjezeka mamasukidwe akayendedwe. .

Covalently cross-linked thickening:Covalent crosslinking ndi kuyika kwapang'onopang'ono kwa ma monomers osagwira ntchito omwe amatha kuchitapo kanthu ndi maunyolo awiri a polima, kulumikiza ma polima awiriwo, kusintha kwambiri mawonekedwe a polima, komanso kukhala ndi kuthekera kwina koyimitsidwa atasungunuka m'madzi.

Kuwonjezeka kwa mgwirizano: Ndi mtundu wa polima wosungunuka m'madzi wa hydrophobic, womwe uli ndi mawonekedwe amtundu wa surfactant. The ndende ya polima m'madzi kumawonjezera kugwirizana pakati mamolekyu, ndi interacts ndi hydrophobic gulu la polima pamaso pa surfactant, motero kupanga padziko yogwira Wosakaniza micelles wothandizila ndi polima hydrophobic magulu, motero kuonjezera kukhuthala kwa njira.

03 Gulu la zonenepa

Malinga ndi kusungunuka kwa madzi, chitha kugawidwa kukhala: madzi osungunuka m'madzi ndi micropowder thickener. Malinga ndi thickener gwero akhoza kugawidwa mu: zachilengedwe thickener, kupanga thickener. Malingana ndi ntchito, ikhoza kugawidwa kukhala: madzi opangira madzi, mafuta opangira mafuta, acidic thickener, alkaline thickener.

04 Zokhuthala wamba

1. Natural madzi sungunuka thickener

wowuma:Gel imatha kupangidwa m'madzi otentha, hydrolyzed ndi michere yoyamba kukhala dextrin, kenako kukhala maltose, ndipo pamapeto pake imapangidwa ndi hydrolyzed kukhala shuga. Muzodzoladzola, zitha kugwiritsidwa ntchito ngati gawowa ufa waiwisizipangizo mu zodzikongoletsera ufa mankhwala ndi zomatira mu rouge. ndi thickeners.

xanthan chingamu:Imasungunuka mosavuta m'madzi ozizira ndi madzi otentha, imakhala ndi kukana kwa ion, ndipo imakhala ndi pseudoplasticity. The mamasukidwe akayendedwe amachepetsa koma recoverable pansi kumeta ubweya. Nthawi zambiri amagwiritsidwa ntchito ngati thickener mu masks amaso, essences, toner ndi ena othandizira madzi. Khungu limakhala losalala komanso limapewa zokometsera. Zosungirako za ammonium zimagwiritsidwa ntchito palimodzi.

Sclerotin:Gel 100% yachilengedwe, yankho la scleroglucan lili ndi kukhazikika kwapadera pa kutentha kwakukulu, limagwira ntchito bwino pamitundu yambiri ya pH, ndipo limalekerera kwambiri ma electrolyte osiyanasiyana mu yankho. Ili ndi digiri yapamwamba ya pseudoplasticity, ndipo kukhuthala kwa yankho sikumasintha kwambiri ndi kukwera ndi kugwa kwa kutentha. Lili ndi zotsatira zonyezimira komanso kumveka bwino kwa khungu, ndipo nthawi zambiri amagwiritsidwa ntchito mu masks amaso ndi zinthu.

Gum Gum:Ndiwosungunuka kwathunthu m'madzi ozizira komanso otentha, koma osasungunuka mumafuta, mafuta, ma hydrocarbons, ketoni ndi esters. Ikhoza kumwazikana m'madzi otentha kapena ozizira kupanga viscous madzi, mamasukidwe akayendedwe a 1% amadzimadzi njira ndi 3 ~ 5Pa · s, ndipo njira zambiri wosalowerera.

sodium alginate:Pamene pH = 6-9, mamasukidwe akayendedwe ndi khola, ndi asidi alginic akhoza kupanga colloidal mpweya ndi ayoni kashiamu, ndi alginic asidi gel osakaniza akhoza precipitated mu acidic chilengedwe.

carrageenan:Carrageenan ali ndi kukana kwa ayoni wabwino ndipo satengeka ndi kuwonongeka kwa enzymatic monga zotumphukira za cellulose.

2. Semi-synthetic madzi sungunuka thickener

Methylcellulose:MC, madzi amafufuma kukhala omveka bwino kapena pang'ono turbid colloidal solution. Kuti musungunuke methylcellulose, choyamba mumwaze madzi enaake akakhala otsika kuposa kutentha kwa gel osakaniza, kenaka yikani madzi ozizira.

Hydroxypropylmethylcellulose:HPMC ndi non-ionic thickener, amene amafufuma mu bwino kapena pang'ono turbid colloidal njira m'madzi ozizira. Ili ndi zotsatira zabwino zowonjezeretsa thovu komanso kukhazikika mu makina ochapira amadzimadzi, imathandizira kusasinthika kwadongosolo, ndipo imakhala ndi mphamvu yolumikizirana ndi ma cationic conditioners, bwino kuwongolera magwiridwe antchito a Wet combing, alkali imatha kufulumizitsa kusungunuka kwake, ndikuwonjezera pang'ono mamasukidwe akayendedwe, hydroxypropyl methylcellulose ndi khola mchere wamba, koma pamene ndende ya mchere yankho ndi mkulu, mamasukidwe akayendedwe a hydroxypropyl methylcellulose njira kuchepetsa chizolowezi kuwonjezeka.

Wowuma wa sodium carboxymethyl: CMC-Na, pamene digiri ya m'malo ndi wamkulu kuposa 0,5, mosavuta sungunuka m'madzi kupanga colloid mandala; CMC ndi digiri ya m'malo otsika kuposa 0,5 ndi insoluble m'madzi, koma akhoza kusungunuka mu njira zamchere amadzimadzi. CMC nthawi zambiri amakhalapo mu mawonekedwe a Mipikisano maselo aggregates m'madzi, ndi mamasukidwe akayendedwe apamwamba kwambiri. Pamene kutentha kumawonjezeka, kukhuthala kumachepa. Pamene pH ndi 5-9, kukhuthala kwa yankho kumakhala kokhazikika; pamene pH ili yosakwana 3, hydrolysis imachitika pamene mpweya umapezeka; pamene pH ndi yaikulu kuposa 10, kukhuthala kumachepa pang'ono. Kukhuthala kwa njira ya CMC kudzachepanso pansi pa zochita za tizilombo. Kulowetsedwa kwa ayoni a calcium mu njira yamadzi ya CMC kudzayambitsa turbidity, ndipo kuwonjezera kwa ayoni achitsulo apamwamba kwambiri monga Fe3 + ndi Al3 + kungayambitse CMC kugwa kapena kupanga gel. Nthawi zambiri, phala ndi lovuta kwambiri.

Hydroxyethyl cellulose:HEC, thickener, suspending wothandizira. Itha kupereka rheology yabwino, kupanga filimu komanso kunyowa. Mkulu bata, ndi zomata khungu kumverera, zabwino kwambiri ayoni kukana, izo zambiri tikulimbikitsidwa kumwazikana m'madzi ozizira ndiyeno kutentha ndi kusonkhezera kupasuka homogeneously.

PEG-120 Methyl Glucose Dioleate:Amagwiritsidwa ntchito mwapadera ngati shampu, shawa gel, zotsukira kumaso, zotsukira m'manja, zochapira ana, ndi shampu yopanda misozi. Ndiwothandiza kwambiri kwa ma surfactants ena omwe ndi ovuta kukhuthala, ndipo PEG-120 methyl glucose dioleate sakwiyitsa maso. Ndi yabwino kwa mwana shampu ndi kuyeretsa mankhwala. Amagwiritsidwa ntchito mu shampoos, zoyeretsa kumaso, The AOS, AES mchere wa sodium, mchere wa sulfosuccinate ndi ma amphoteric surfactants omwe amagwiritsidwa ntchito posamba gel osamba amakhala ndi zotsatira zabwino zophatikizira komanso kukhuthala,
