Ndi hydroxyellulose yoyaka

Hydroxyethycellulose (hec) ndi polymer yopanda madzi, yosungunuka yochokera ku cellulose. Nthawi zambiri imagwiritsidwa ntchito m'mafakitale osiyanasiyana monga mankhwala, zodzoladzola, chakudya, komanso zopangidwa ndi anthu chifukwa cha kukula kwake, kukhazikika, komanso kugwedeza katundu.

Kapangidwe ka mankhwala a hydroxyellulose

Hec ndi cellulose yosinthidwa polymer, pomwe magulu a hydroxyethyl amayambitsidwa pamphepete mwa nyanjayo. Kusintha kumeneku kumawonjezera kusungunuka kwamadzi ndi zina za cellulose. Magulu a hydroxyethyl (-ch2ch2oh) amalumikizidwa bwino ku Hydroxyl (-oh) ma molekyulu. Kusintha kumeneku kumasintha zinthu zakuthupi ndi mankhwala a cellulose, kupangitsa kukhala koyenera kwa mapulogalamu osiyanasiyana.

Mikhalidwe yodzikongoletsera

1. Kuphatikiza

Cellulose yoyera ndi zinthu zoyaka chifukwa zili ndi magulu a hydroxyl, omwe amatha kuphatikizika. Komabe, kukhazikitsidwa kwa ma hydroxyethyl magulu a cellulose amasintha mawonekedwe ake. Kupezeka kwa magulu a hydroxyethyl kumatha kukhudza machitidwe a shec poyerekeza ndi cellulose wosavomerezeka.

2. Kuyesa kwa Flammabity

Kuyesa kwa Flammality ndikofunikira kudziwa zoopsa za moto zomwe zimagwirizanitsidwa ndi zinthu. Mayeso osiyanasiyana ofunikira, monga atsikana amm e84 (njira yoyeserera yoyaka moto) ndi Ul 94 (muyezo wotetezeka), amagwiritsidwa ntchito kuwunika zathupi. Mayeso awa amayesa magawo ngati lawi, kukula utsi, ndikuwonetsa.

Zinthu Zomwe Zimakhudza Chinyengo

1. Zolemba

Kukhalapo kwa chinyontho kumatha kusintha chochita cha zinthu. Zipangizo zama celluloosic nthawi zambiri zimakhala zoyaka pang'ono pomwe zimakhala ndi chinyezi chambiri chifukwa cha kutentha kwa mayamwidwe ndi kuzizira kwamadzi. Hydroxyethylcellulose, posungunuka madzi, atha kukhala ndi chinyezi chosiyanasiyana malinga ndi chilengedwe.

2. Kukula kwa tinthu ndi kachulukidwe

Kukula kwa tinthunthu komanso kachulukidwe ka zinthu kamatha kukhudza kufooka kwake. Zipangizo zogawanika bwino nthawi zambiri zimakhala ndi malo okwera, omwe amalimbikitsa kuyaka mwachangu. Komabe, hec imagwiritsidwa ntchito ngati mawonekedwe ophatikizika kapena granated ndi tinthu olamulidwa ndi tinthu tating'onoting'ono tomwe timafunikira kuti tikwaniritse zofunika pa ntchito.

3. Kukhalapo kwa zowonjezera

Pamapulogalamu othandiza, hydroxyathylluthyllulose imatha kukhala ndi zowonjezera monga ma pulasitiki, okhazikika, kapena moto wotopa. Izi zowonjezera zimatha kusintha mawonekedwe a Flammairtiality pazogulitsa za Hec. Mwachitsanzo, flame oyang'anira obwereza amatha kupondereza kapena kuchepetsedwa ndikufalikira.

Zowopsa zamoto ndi malingaliro achitetezo

1. Kusunga ndi kugwirira

Kusunga koyenera komanso kusamalira machitidwe ndikofunikira kuti muchepetse ngozi ya moto. Hydroxyenulose iyenera kusungidwa pamalo owuma, otetezedwa bwino kutali ndi zinthu zomwe zingachitike. Chisamaliro chiyenera kutengedwa kuti muchepetse kutentha kwambiri kapena kuwala kwa dzuwa, komwe kumatha kuwongolera kapena kuwonongeka.

2. Kutsatira

Opanga ndi ogwiritsa ntchito ma hydroxenulose omwe ali ndi zinthu zokhala ndi ayenera kutsatira malamulo ndi mfundo zina. Mabungwe owongolera monga ntchito yosungirako zinthu zachilengedwe ndi zaumoyo ku United States ndi mankhwala aku Europe Agency (ECHA) ku European ku European ku European Union amapereka malangizo oyenera komanso kugwiritsa ntchito mankhwala.

3.. Zokambirana zamoto

Ngati moto wokhudzana ndi hydroxyathycellulose kapena zinthu zomwe zili ndi hec, zoyeserera zowona ziyenera kuperekedwa. Izi zingaphatikizepo kugwiritsa ntchito madzi, mpweya woipa, zowumitsa zamankhwala, kapena chithovu, kutengera mtundu wa Moto ndi chilengedwe.

Hydroxyellulose ndi collulose polymer polymer nthawi zambiri amagwiritsidwa ntchito m'mafakitale osiyanasiyana chifukwa chokhazikika komanso kulimbitsa thupi. Ngakhale cellulose yoyera imayaka, kukhazikitsa kwa hydroxethyl kumasintha mawonekedwe a Hec. Zinthu monga chinyezi, kukula kwa tinthu, kachulukidwe, ndipo kupezeka kwa zowonjezera kumatha kupangitsa kuti mtundu wa hydroxyellulose okhala ndi zinthu zina. Kusunga koyenera, kugwira ntchito, komanso kutsatira malamulo otetezedwa ndikofunikira kuti muchepetse ngozi zowopsa zokhudzana ndi HeC. Kafukufuku wina komanso kuyezetsa kungakhale kofunikira kuti mumvetsetse bwino za hydroxyellulose okhazikika pansi pamikhalidwe yosiyanasiyana.
