HPMC YB 510M

EipponCell HPMC YB510M ndi sing'anga kukhuthala kwama cellulose ether.Njira yopangira ma cellulose ether imaphatikizapo kugwiritsa ntchito thonje / thonje zamkati / zamkati zamatabwa monga zopangira zoyambira, zomwe zimapangidwa ndi alkaline kuti zipeze cellulose.Pambuyo pake, propylene oxide ndi methyl chloride adawonjezeredwa kuti apangitse etherification, zomwe zidapangitsa kupanga cellulose ether.Wodziwika kuti "industrial monosodium glutamate," cellulose ether ili ndi zinthu zapadera, kuphatikiza kukhuthala kwa njira, kusungunuka kwamadzi, kuyimitsidwa kapena kukhazikika kwa latex, kuthekera kopanga filimu, kusunga madzi, ndi kumamatira.

Pankhani ya EipponCell HPMC YB510M, imagwira ntchito ngati hydroxypropyl methyl cellulose yomwe imagwiritsidwa ntchito mu utoto wamadzi ndi zochotsa utoto.Ether ya cellulose iyi imapereka phindu lofunikira pamapulogalamuwa.Imathandizira kukulitsa yankho la penti, kuwonetsetsa kuti ikugwirizana bwino komanso kuphimba bwino pakagwiritsidwa ntchito.Kuphatikiza apo, imawonetsa kusungunuka kwamadzi kwabwino, kulola kusakanikirana kosavuta ndikukonzekera utoto wamadzi.Cellulose ether imathandizanso kukhazikika kwa kuyimitsidwa, kuteteza ma pigment kuti asakhazikike ndikuwonetsetsa kugawidwa kofanana mu utoto wonse.Ndipo, imathandizira kupanga filimu yokhazikika pamtunda wopaka utoto, kupititsa patsogolo moyo wautali ndi chitetezo cha utoto.

Kuphatikiza apo, EipponCell HPMC YB510M imawonetsa kusungirako bwino kwa madzi, kusunga njira ya utoto kuti ikhale yogwira ntchito kwa nthawi yayitali, kuchepetsa chiopsezo cha kuyanika kapena kupukuta.Amaperekanso zinthu zomatira, zomwe zimalimbikitsa mgwirizano wamphamvu pakati pa utoto wopaka utoto ndi filimu ya utoto, zomwe zimapangitsa kuti zikhale zolimba komanso zolimba kuti zisamaphwanye kapena kuphulika.

Kugwiritsa ntchito HPMC YB 510M

EipponCell HPMC YB 510M itha kugwiritsidwa ntchito mu utoto wamadzi ndi zochotsa utoto.Zochotsa utoto ndi zinthu, mwina zosungunulira kapena phala, zopangidwa kuti zisungunuke kapena kutupa filimu zokutira.Amapangidwa makamaka ndi zosungunulira zamphamvu, parafini, cellulose ether, pakati pa zinthu zina.

Popanga zombo zapamadzi, njira zosiyanasiyana zamakina monga fosholo pamanja, kuphulitsa kuwombera, kuphulika kwa mchenga, madzi othamanga kwambiri, ndi ma jets abrasive amagwiritsidwa ntchito pochotsa zokutira zakale.Komabe, pochita ndi zida za aluminiyamu, njira zamakinazi zimatha kukanda pamwamba pa aluminiyumu.Chifukwa chake, kupukuta kwa sandpaper ndi kuchotsa utoto nthawi zambiri kumagwiritsidwa ntchito ngati njira yoyamba yochotsera filimu yakale ya utoto.

Ubwino wogwiritsa ntchito utoto wochotsa utoto umaphatikizapo kugwiritsa ntchito bwino kwambiri, kutentha kwa chipinda, kuwononga pang'ono kwa zitsulo, kugwiritsa ntchito kosavuta, komanso kusafunikira zida zowonjezera. .Kupanga zinthu zatsopano zochotsera utoto, kuphatikizapo njira zopangira madzi, zakhala zikuchulukirachulukira m'zaka zaposachedwa. zinthu zoyaka moto pang'onopang'ono zafala kwambiri pamsika wochotsa utoto.

Mfundo yochotsera utoto

Njira yoyamba yochotsera utoto imadalira kugwiritsa ntchito zosungunulira za organic kuti asungunuke ndi kutupa mitundu yosiyanasiyana ya mafilimu opaka utoto, potero amathandizira kuchotsedwa kwa zigawo zakale za utoto kuchokera pagawo laling'ono.Chochotsa utoto chikalowa mipata pakati pa maunyolo a polima mkati mwa zokutira, zimayambitsa kutupa kwa polima.Zotsatira zake, kuchuluka kwa filimu yophimbidwa kumawonjezeka, zomwe zimapangitsa kuchepetsa kupsinjika kwamkati komwe kumapangidwa ndi polima yokulirapo.Pamapeto pake, kufooka kumeneku kwa kupsinjika kwamkati kumasokoneza kumamatira pakati pa filimu yophimbidwa ndi gawo lapansi.

Pamene chochotsa utotocho chikupitirizabe kuchitapo kanthu pa filimu yophimbidwa, imayamba kuchoka pa kutupa komweko kupita ku kutupa kwa pepala lalikulu.Izi zimapangitsa kuti makwinya apangidwe mkati mwa filimu yophimbidwa ndipo pamapeto pake amalepheretsa kumamatira kwake ku gawo lapansi.

Kupyolera mu njirayi, organic zosungunulira mu chochotsa utoto bwino kuswa zomangira mankhwala mkati ❖ kuyanika filimu, kufooketsa umphumphu wake structural ndi kupanga mikhalidwe ya kuchotsedwa kwake. kupentanso kapena ntchito zina.

Gulu la chochotsa utoto

Ojambula utoto amatha kugawidwa m'mitundu iwiri ikuluikulu kutengera mtundu wazinthu zopangira mafilimu zomwe amachotsa.Mtundu woyamba umagwiritsa ntchito zosungunulira za organic monga ma ketoni, benzene, ndi parafini ya volatilization retarder (yomwe imadziwika kuti lotion yoyera).Zochotsa utotozi zimagwiritsidwa ntchito makamaka kuchotsa mafilimu akale a utoto opangidwa ndi mafuta, alkyd-based, kapena nitro-based paints.Amapangidwa ndi zosungunulira za organic, zomwe zimatha kuwonetsa kuyaka komanso kawopsedwe.Komabe, ndi zotsika mtengo.

Mtundu wachiwiri wochotsa utoto ndi chlorinated hydrocarbon formulation, yomwe imakhala ndi dichloromethane, parafini, ndi cellulose ether.Mtundu uwu nthawi zambiri umatchedwa chochotsa utoto wonyezimira.. Amagwiritsidwa ntchito makamaka kuchotsa zokutira zakale zochiritsidwa monga epoxy asphalt, polyurethane, epoxy polyethylene, kapena amino alkyd resins. otsika kawopsedwe, ndi osiyanasiyana ntchito.

Zochotsa utoto zomwe zili ndi dichloromethane monga zosungunulira zoyambira zimathanso kugawidwa motengera pH. Zimagawidwa m'magawo ochotsa utoto omwe ali ndi pH pafupifupi 7±1, ochotsa utoto wamchere wokhala ndi pH yamtengo pamwamba pa 7, ndi ochotsa utoto wa acidic. ndi pH mtengo wotsika.

Mitundu yosiyanasiyana ya zochotsa utoto izi zimapereka njira zochotseramo bwino mitundu yeniyeni ya mafilimu a utoto, kupereka mitundu yosiyanasiyana ya kawopsedwe, kuchita bwino, komanso kuyenerera kugwiritsa ntchito.. Ndikofunikira kusankha chochotsa utoto choyenera kutengera zokutira komwe kumayenera kuchotsedwa komanso zofunika chitetezo ndi magwiridwe antchito.
