Thickenersanoshandiswa zvakanyanya, uye tsvakiridzo yemazuva ano yekushandisa yakabatanidzwa zvakanyanya mukudhinda nekudhaya machira, machira ane mvura, mushonga, kugadzira chikafu uye zvinodiwa zvezuva nezuva.
1. Kudhinda nekudhaya machira
Machira uye kudhinda kudhinda kuti uwane yakanaka yekudhinda mhedzisiro uye mhando, kusvika pamwero mukuru zvinoenderana nekuita kwekudhinda paste, umo kuita kwe thickener kunoita basa rakakosha. Kuwedzerwa kweiyo thickening agent inogona kuita kuti chigadzirwa chekudhinda chipe ruvara rwepamusoro, chinyorwa chekudhinda chakajeka, ruvara rwakajeka uye ruzere, kuvandudza chigadzirwa permeability uye thixotropy, uye kugadzira yakakura purofiti nzvimbo yekudhinda nekudhaya mabhizinesi. Iyo thickening agent yekudhinda paste yaimbove yakasikwa starch kana sodium alginate. Nekuda kwekuoma kwekunamira kwechisikigo starch uye mutengo wepamusoro wesodium alginate, zvishoma nezvishoma inotsiviwa ne acrylic kudhinda uye dyeing thickening agent.
2. Pendi yakagadzirwa nemvura
Basa guru repende nderokushongedza nekudzivirira chinhu chakaputirwa. Kuwedzera kwakakodzera kweiyo thickener kunogona kunyatso shandura maitiro emvura eiyo coating system, kuitira kuti ive nethixotropy, kuitira kuti ipe iyo coating yakanaka yekuchengetedza kugadzikana uye zvivakwa zvekushandisa. A good thickener inofanira kusangana nezvinodiwa zvinotevera: kuvandudza viscosity yekuputira panguva yekuchengetedza, kudzivisa kupatsanurwa kwejasi, kuderedza viscosity panguva yekupenda kwepamusoro, kuvandudza viscosity yefirimu yekuvhara mushure mekupenda, kudzivirira kuitika kwekuyerera kwakarembera. chiitiko, zvichingodaro. Tsika dzakakora dzinowanzo shandisa mapolima anonyungudika nemvura, akadai sehydroxyethyl cellulose (HEC), polima mune zvinobuda muselulosi. SEM data inoratidza kuti iyo polymer thickener inogona zvakare kudzora kuchengetwa kwemvura panguva yekupfekedzwa kwezvigadzirwa zvemapepa, uye kuvapo kwegobvu kunogona kuita kuti pamusoro pebepa rakaputirwa rive rakatsetseka uye yunifomu. Kunyanya, iyo yekuzvimba emulsion (HASE) thickener ine yakanakisa spattering resistance uye inogona kushandiswa pamwe chete nemamwe marudzi ehukobvu kuti kuderedze zvakanyanya kushata kwepepa rekuputira.
3: Zvokudya
Kusvika pari zvino, kune anopfuura makumi mana emhando dzekudya dzakakora maajenti anoshandiswa muindasitiri yechikafu munyika, ayo anonyanya kushandiswa kuvandudza uye kudzikamisa zvimiro zvemuviri kana mafomu echikafu, kuwedzera viscosity yechikafu, kupa chikafu chinotsvedza kuravira, uye. kuita basa mukukora, kudzikamisa, homogenizing, emulsifying gel, masking, kugadzirisa kuravira, kuwedzera kunaka, uye kutapira. Kune akawanda marudzi emakobvu, ayo akakamurwa kuita zvakasikwa uye makemikari synthesis. Natural thickeners inonyanya kuwanikwa kubva kuzvirimwa nemhuka, uye makemikari synthesis thickeners anosanganisira CMC-Na, propylene glycol alginate uye zvichingodaro.
4. Zuva nezuva indasitiri yemakemikari
Parizvino, kune anopfuura mazana maviri makobvu anoshandiswa muindasitiri yemakemikari yemazuva ese, kunyanya inorganic munyu, ma surfactants, mapolymer anonyungudika nemvura uye madoro ane mafuta nemafuta acids. Panyaya yezvinodiwa zvezuva nezuva, inoshandiswa kugezesa mvura, inogona kuita kuti chigadzirwa chive pachena, chigadzikane, chakapfuma mufuro, chakapfava muruoko, chiri nyore kugeza, uye chinowanzoshandiswa muzvizoro, mushonga wemazino, nezvimwe.
5. Zvimwe
Thickener zvakare ndiyo inonyanya kuwedzera mumvura-based fracturing fluid, iyo ine hukama nekuita kweiyo fracturing fluid uye kubudirira kana kukundikana kwekutsemuka. Mukuwedzera, thickeners anoshandiswawo zvakanyanya mumishonga, kugadzira mapepa, ceramics, dehwe processing, electroplating nezvimwe zvinhu.
