Kugawidwa malinga ndi zinthu zina,ethers a celluloseZingagawidwe m'magulu a single ethers ndi mixed ethers; malinga ndi kusungunuka, cellulose ethers zingagawidwe m'magulu osungunuka m'madzi ndi osasungunuka m'madzi.
Njira yayikulu yogawa ma cellulose ether ndiyo kugawa malinga ndi ionization:
Malinga ndi ionization, cellulose ether ingagawidwe m'magulu osakhala a ionic, ionic ndi mitundu yosakanikirana.
Ma ether a cellulose omwe si a ionic akuphatikizapo hydroxypropyl methyl cellulose, methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose ndi hydroxyethyl methylcellulose, omwe ethyl cellulose sasungunuka m'madzi.
Ionic cellulose ndi sodium carboxymethyl cellulose.
Ma cellulose osakanikirana ndi monga hydroxyethyl carboxymethyl cellulose ndi hydroxypropyl carboxymethyl cellulose.
Udindo wa efa wa cellulose:
Gawo la zomangamanga:
Mtondo wa miyala umatha kusunga madzi ndi kukhuthala, kukulitsa kugwirira ntchito, kukonza mikhalidwe yomangira, komanso kuwonjezera magwiridwe antchito.
Chophimba chakunja cha khoma chimatha kuwonjezera mphamvu yosungira madzi mu chophimbacho, kupititsa patsogolo kusinthasintha kwa madzi ndi kapangidwe kake, kulimbitsa mphamvu yoyambirira ya chophimbacho ndikupewa kusweka.
Chomangira matailosi chingathandize kuti chomangira matailosi chisamagwedezeke, kulimbitsa mphamvu yomangira matailosi, komanso kuletsa mphamvu yodula matailosi kuti asagwedezeke.
Chomangira chodziyimira payokha, chomwe chingathandize kuti chomangiracho chiziyenda bwino komanso kuti chisamayende bwino, komanso chingathandize kumanga.
Putty yosalowa madzi, imatha kusintha guluu wachikhalidwe wa mafakitale, kukonza kusunga madzi, kukhuthala, kukana kutsuka ndi kumamatira kwa putty, ndikuchotsa kuopsa kwa formaldehyde.
Dothi la gypsum lingathandize kukhuthala, kusunga madzi komanso kuchedwetsa kuuma.
Utoto wa latex, umatha kukhuthala, kuletsa kusungunuka kwa utoto, kuthandiza kufalikira kwa utoto, kukonza kukhazikika ndi kukhuthala kwa latex, komanso kuthandizira magwiridwe antchito a kapangidwe kake.
PVC, imatha kugwira ntchito ngati chotulutsira madzi, kusintha kuchuluka kwa utomoni wa PVC, kusintha kukhazikika kwa kutentha kwa utomoni ndikuwongolera kukula kwa tinthu, kukonza mawonekedwe akuthupi, mawonekedwe a tinthu ndi kusungunuka kwa zinthu za utomoni wa PVC.
Zoumbaumba, zingagwiritsidwe ntchito ngati chomangira cha ceramic glaze slurry, chomwe chingayimitse, kumasula, ndikusunga madzi, kuwonjezera mphamvu ya glaze yaiwisi, kuchepetsa kuchepa kwa glaze youma, ndikupangitsa kuti thupi la mwana wosabadwayo ndi glaze zikhale zolimba komanso zosavuta kugwa.
Gawo la mankhwala:
Kukonzekera kokhazikika komanso kolamulidwa kungathandize kuti mankhwala azituluka pang'onopang'ono komanso mosalekeza popanga zinthu zomangira mafupa, kuti nthawi yogwira ntchito ya mankhwala ichepe.
Makapisozi a masamba, kuwapanga kukhala gel ndi filimu, kupewa kusakanikirana ndi kuchira.
Kuphimba piritsi, kuti lipakedwe pa piritsi lokonzedwa kuti likwaniritse zolinga izi: kupewa kuwonongeka kwa mankhwala ndi mpweya kapena chinyezi mumlengalenga; kupereka njira yofunikira yotulutsira mankhwala pambuyo popereka; kubisa fungo loipa kapena fungo la mankhwala kapena kukonza mawonekedwe ake.
Zomangira zomangira, zomwe zimachepetsa liwiro la tinthu ta mankhwala m'kati mwa zinthu zonse mwa kuwonjezera kukhuthala.
Zomangira mapiritsi zimagwiritsidwa ntchito panthawi ya granulation kuti zipangitse kuti tinthu ta ufa timalumikizana.
Mapiritsi osungunuka, omwe angapangitse kuti mankhwalawa asungunuke kukhala tinthu tating'onoting'ono mu chokonzekera cholimba kuti athe kufalikira kapena kusungunuka mosavuta.
Munda wa chakudya:
Zowonjezera zokometsera, zimatha kusintha kukoma, kapangidwe ndi kapangidwe kake; zimawongolera mapangidwe a makhiristo a ayezi; zimakhuthala; zimaletsa kutaya chinyezi cha chakudya; zimapewa kudzaza.
Chowonjezera cha zokometsera, chimatha kukhuthala; chimawonjezera kumamatira ndi kukoma kosalekeza kwa msuzi; chimathandiza kukhuthala ndi mawonekedwe.
Zowonjezera zakumwa nthawi zambiri zimagwiritsa ntchito ether ya cellulose yosakhala ionic, yomwe imagwirizana ndi zakumwa; zimathandiza kuyimitsa; zimakhuthala, ndipo siziphimba kukoma kwa zakumwa.
Chowonjezera chophikira chakudya, chimathandiza kukonza kapangidwe kake; kuchepetsa kuyamwa kwa mafuta; kuletsa kutaya chinyezi cha chakudya; kupangitsa kuti chikhale cholimba kwambiri, ndikupangitsa kapangidwe ka pamwamba ndi utoto kukhala kofanana; kumamatira bwino kwaether ya celluloseKukoma kwa ufa kungathandize kulimbitsa, kusinthasintha, ndi kusinthasintha kwa zinthu zomwe zimapangidwa ndi ufa.
Finyani zowonjezera chakudya kuti muchepetse kupanga fumbi; onjezerani kapangidwe ndi kukoma.
