Mu makampani opanga utoto, kukhazikika ndi kusinthasintha kwa utoto wa utoto ndikofunikira kwambiri. Komabe, panthawi yosungira ndi kugwiritsa ntchito, utoto wa utoto nthawi zambiri umakhala ndi mavuto monga kukhuthala ndi kusakanikirana, zomwe zimakhudza momwe kapangidwe kake kamagwirira ntchito komanso mtundu wake.Hydroxyethyl cellulose (HEC), monga chokhuthala cha polima chosungunuka m'madzi, chimagwira ntchito yofunika kwambiri popanga utoto. Chingathe kusintha bwino mawonekedwe a utoto wa phala, kupewa kusonkhana, komanso kukonza kukhazikika kwa malo osungira.
1. Zifukwa za kukhuthala ndi kusakanikirana kwa utoto wa utoto
Kukhuthala ndi kusakanikirana kwa utoto wa utoto nthawi zambiri kumakhudzana ndi zinthu zotsatirazi:
Kufalikira kwa utoto kosakhazikika: Tinthu ta utoto mu utoto wa utoto tingathe kugwedezeka ndikukhazikika panthawi yosungidwa, zomwe zimapangitsa kuti pakhale kuchuluka kwa utoto m'deralo komanso kusonkhana kwa utoto.
Kutuluka kwa madzi m'dongosolo: Pa nthawi yosungira, kutuluka kwa madzi m'madzi ena kudzachititsa kuti kukhuthala kwa mtundu wa phala kuchuluke, komanso kupanga zinthu zouma pamwamba.
Kusagwirizana pakati pa zowonjezera: Zothina zina, zosakaniza kapena zowonjezera zina zimatha kukumana, zomwe zimakhudza mawonekedwe a rheological a phala la mtundu, zomwe zimapangitsa kuti kukhuthala kosazolowereka kapena kupanga flocculent kuchuluke.
Mphamvu yodula: Kusakaniza kapena kupopera makina kwa nthawi yayitali kungayambitse kuwonongeka kwa kapangidwe ka unyolo wa polima m'dongosolo, kuchepetsa kusinthasintha kwa utoto wa phala, ndikupangitsa kuti ikhale yokhuthala kapena yosakanikirana.
2. Njira yogwirira ntchito ya hydroxyethyl cellulose
Hydroxyethyl cellulose (HEC) ndi chinthu chochokera ku cellulose chosakhala cha ionic chomwe chimakhuthala bwino, chimatha kusintha rheological komanso chimakhazikika pakufalikira. Njira yake yayikulu yogwirira ntchito mu utoto wa utoto ndi monga:
Kukhuthala ndi kusintha kwa rheological: HEC imatha kusakanikirana ndi mamolekyu amadzi kudzera mu hydrogen bonding kuti ipange hydration yokhazikika, kuwonjezera kukhuthala kwa dongosolo, kuletsa tinthu ta utoto kuti tisamasonkhanane ndikukhazikika, ndikuwonetsetsa kuti utoto wa utoto umasunga kusinthasintha kwabwino panthawi yoyimirira kapena yomanga.
Dongosolo logawanitsa lokhazikika: HEC ili ndi ntchito yabwino pamwamba, imatha kuphimba tinthu ta utoto, kuwonjezera kufalikira kwawo m'madzi, kupewa kusonkhana pakati pa tinthu tating'onoting'ono, motero kuchepetsa kugwedezeka ndi kusonkhana.
Choletsa kuuma kwa madzi: HEC imatha kupanga gawo linalake loteteza, kuchepetsa kuchuluka kwa madzi omwe amatuluka, kuletsa utoto wa phala kuti usakhuthale chifukwa cha kutayika kwa madzi, ndikuwonjezera nthawi yosungira.
Kukana kumeta: HEC imapatsa utoto thixotropy wabwino, imachepetsa kukhuthala chifukwa cha mphamvu yayikulu yometa, imathandizira kapangidwe kake, ndipo imatha kubwezeretsa kukhuthala msanga chifukwa cha mphamvu yochepa yometa, zomwe zimapangitsa kuti utotowo usagwedezeke.
3. Ubwino wa hydroxyethyl cellulose mu utoto wa utoto
Kuwonjezera hydroxyethyl cellulose ku dongosolo la utoto wa utoto kuli ndi ubwino wotsatira:
Kukonza kukhazikika kwa kusungirako kwa phala la mtundu: HEC imatha kuletsa bwino kusungunuka kwa utoto ndi kusonkhana kwa utoto, kuonetsetsa kuti phala la mtundu limasunga kusinthasintha kofanana pambuyo posungidwa kwa nthawi yayitali.
Kuwongolera magwiridwe antchito a kamangidwe: HEC imapatsa utoto mphamvu zabwino kwambiri za rheological, zomwe zimapangitsa kuti zikhale zosavuta kutsuka, kupukuta kapena kupopera utoto panthawi yomanga, zomwe zimapangitsa kuti utoto ukhale wosinthasintha.
Kuonjezera kukana madzi: HEC ikhoza kuchepetsa kusintha kwa kukhuthala komwe kumachitika chifukwa cha kusungunuka kwa madzi, kotero kuti utoto wa utoto ukhalebe wokhazikika bwino pamikhalidwe yosiyanasiyana yachilengedwe.
Kugwirizana kwamphamvu: HEC ndi chinthu chokhuthala chosakhala cha ionic, chomwe chimagwirizana bwino ndi zinthu zambiri zosungunulira, zinthu zonyowetsa ndi zina zowonjezera, ndipo sichidzayambitsa kusakhazikika kwa dongosolo lopangira.
Chitetezo ndi chitetezo cha chilengedwe: HEC imachokera ku cellulose yachilengedwe, imakwaniritsa zofunikira zoteteza chilengedwe, siitulutsa zinthu zovulaza, ndipo ikugwirizana ndi njira yopangira zophimba zochokera m'madzi zomwe zimateteza zachilengedwe komanso zobiriwira.
4. Kagwiritsidwe ntchito ndi malingaliro a hydroxyethyl cellulose
Kuti mugwire bwino ntchito ya HEC, mfundo zotsatirazi ziyenera kukumbukiridwa mukamagwiritsa ntchito mu fomula yopaka utoto:
Kuwongolera moyenera kuchuluka kwa zowonjezera: Kuchuluka kwa HEC nthawi zambiri kumakhala pakati pa 0.2% -1.0%. Kuchuluka kwa kagwiritsidwe ntchito kuyenera kusinthidwa malinga ndi zosowa za makina ophikira kuti apewe kukhuthala kwambiri ndikukhudza magwiridwe antchito omanga.
Njira yosungunula isanayambe: HEC iyenera kufalikira ndi kusungunuka m'madzi kaye, kenako kuwonjezeredwa ku makina opaka utoto pambuyo popanga yankho lofanana kuti zitsimikizire kuti ikugwira ntchito mokwanira pakukhuthala ndi kufalikira kwake.
Gwiritsani ntchito ndi zowonjezera zina: Zitha kufananizidwa bwino ndi zotulutsira madzi, zinthu zonyowetsa madzi, ndi zina zotero kuti ziwongolere kufalikira kwa utoto ndikuwonjezera magwiridwe antchito a utoto.
Pewani zotsatira za kutentha kwambiri: Kusungunuka kwa HEC kumakhudzidwa kwambiri ndi kutentha. Ndikofunikira kuti musungunuke pa kutentha koyenera (25-50℃) kuti mupewe kusonkhana kapena kusungunuka kosakwanira.
Hydroxyethyl celluloseIli ndi phindu lofunika kwambiri pakugwiritsa ntchito utoto wa utoto. Imatha kuthetsa mavuto okhudzana ndi kukhuthala kwa utoto wa utoto ndi kusonkhana kwa utoto, komanso kukonza kukhazikika kwa malo osungiramo zinthu komanso magwiridwe antchito omanga. Kukhuthala kwake, kukhazikika kwa kufalikira kwa utoto komanso kukana kusungunuka kwa madzi kumapangitsa kuti ikhale yowonjezera yofunika kwambiri pa utoto wopangidwa ndi madzi. Mu ntchito zothandiza, kusintha moyenera mlingo wa HEC ndi njira yowonjezeramo kungapangitse kuti utotowo ukhale wabwino kwambiri ndikuwonjezera mtundu wonse. Ndi chitukuko cha utoto wopangidwa ndi madzi, mwayi wogwiritsa ntchito HEC udzakhala waukulu.
