Udindo wa hydroxypropyl wowuma ether (HPS) ku matope

Wowuma ether ndi mawu ambiri osintha miyala yosinthidwa yokhala ndi zingwe za ether mu Molekyu, zomwe zimagwiritsidwa ntchito kwambiri ngati mankhwala, chakudya, mankhwala ena. Masiku ano timawafotokozera kwambiri gawo la sturch ether mu matope.

Mafala Akutoma Nawo

Zomwe zimagwiritsidwa ntchito kwambiri komanso zogwiritsidwa ntchito nthawi zambiri ndi mbuzi ya mbatata, tapioca yowuma, chimanga chowuma, ndi chotupa chambiri, chotupa cham'mila ndi tapioca.

Wowuma ndi polysacharide macromaror course yopangidwa ndi glucose. Pali mitundu iwiri ya mamolekyulu, mzere ndi nthambi, yomwe imatchedwa Amylose (pafupifupi 20%) ndi amylopectin (pafupifupi 80%). Pofuna kusintha zomwe zimagwiritsidwa ntchito popanga zida zomangira, njira zakuthupi ndi zamankhwala zitha kugwiritsidwa ntchito kuzisintha kuti zitheke kupanga zinthu zosiyanasiyana.

Wopukutira wosungunuka umaphatikizapo mitundu yosiyanasiyana ya zinthu. Monga Carboxymethyl wowuma ether (ma cms), hydroxypyl ether ether (ma sps), hydroxethyl ether (hes), etc.

Udindo wa hydroxypropyl wowuma ether mu matope

1) Kukulitsa matope, kuwonjezera odana ndi kusamba, osakanikirana ndi mitundu ya matope

Mwachitsanzo, pomanga tile zomatira, zomata, ndi matope opatsirana pamatope amathandizidwe, makamaka gysyumu yochokera ku gypsum imafunikira kuti ikhale yovuta kwambiri koma ingathetse kufooka kumeneku.
Madzimadzi ndi kukana kwa Abeg nthawi zambiri kumakhala kotsutsana kwambiri, ndipo madzi ambiri amachepetsa kuchepa kwa kukana kwa salg. Matope ndi zitamba zotsutsana ndi zotsutsana kotero, ndiye kuti, pamene kukakamiza kwakunja, kumawonjezera kugwirira ntchito ndi kuponderezedwa, ndipo mphamvu yakunja imachulukana ndipo kusamvana kumawonjezeka.
Pazinthu zomwe zikuwonjezereka za mataile, kuwonjezera g yozizira imatha kukonza kukana kwa matayala.
2) maola otseguka
Kwa zomata za mataile, zitha kukwaniritsa zofunikira za zomata zam'madzi zapadera (kalasi e, 20min zidawonjezera mpaka 30min kuti mufikire 0.5mm) yomwe imakulitsa nthawi yotseguka.

Kumasintha malo

Stuther ether imatha kupanga mawonekedwe a gypsum base ndi simenti yokha yosalala, yosavuta kuyika, ndipo imakhala okongoletsera bwino. Ndizopindulitsa kwambiri chifukwa cha matope ndi matope opyapyala odzikongoletsera oterewa.
Makina a machitidwe a hydroxypropyl wowuma ether

Mukasungunuka ether amasungunuka m'madzi, udzakhala wopanda fanizo m'matavala a simenti. Popeza wowuma Ether Moleklule ali ndi ma netiweki ndipo amalipitsidwa kwambiri, zimatenga mtengo wolumikizirana kuti athe kulumikizana ndi simenti kapena kuwongolera kapena kutsutsa.
Kusiyana pakati pa hydroxypropyl wowuma ether ndi cellulose ether

1.

Cellulose ether nthawi zambiri imatha kungosintha ma visction ndi kusungidwa kwamadzi kwa dongosolo koma sangathe kukonza zotsutsa komanso zoletsa.

2. Kukula ndi mafayilo

Nthawi zambiri, mafayilo a ether ether ali pafupifupi masauzande, pomwe mamasukidwe a ether ndi mazana angapo mpaka angapo, koma izi sizitanthauza kuti malo owuma a ether, ndi makina owuma cha awiriwo ndi osiyana.

3. Kutsutsa

Poyerekeza ndi cellulose edrs, zotumra manja zitha kuwonjezera mtengo wopatsa zipatso zomata za mataile, potero akuwongolera zida zawo zotsutsa.

4..

Cellulose ether imakhala ndi katundu wolimba wamagetsi, pomwe wosungunuka ether alibe katundu wopatsa mpweya.

5. Mapangidwe a maselo a cellulose

Ngakhale onse owuma ndi ma cellose amapangidwa mamolekyulu owoneka bwino, njira zawo zophatikizira ndizosiyana. Kulowetsa mamolekyu onse owuma mu wowuma ndi chimodzimodzi, pomwe za cellulose ndi zotsutsana, ndipo kumayendedwe a shuga moyandikana ndi mbali iliyonse. Kusiyana kosiyanasiyana kumeneku kumatsimikiziranso kusiyana mu katundu wa cellulose ndi wowuma.
