ʻAʻohe sulfur i loko o ka mea hoʻoponopono kaumaha molekala, ʻaʻohe ona ʻala, palekana a pili aloha i ke kaiapuni a ua hōʻoia ʻia e ka FDA Hoʻohana nui ʻia i nā ʻano resin acrylic like ʻole styrene, ABS, ACRMBS, styrene-acrylic latex nitrile latex butadiene latex e like me ka polymerization reaction He mea hoʻoponopono kaumaha molekala palekana ʻōmaʻomaʻo maoli ia, mea hoʻoili kaulahao, mea hoʻopau kaulahao a me ka mea hoʻololi polymer.
1. I ke kaʻina hana o ka acrylic resin a me ka acrylic ester polymerization, hiki i ka hoʻohui ʻana i kēia huahana ke hoʻoponopono pono i ke kaumaha molekala o ka resin. He haʻahaʻa ke kaumaha molekala o ka acrylic resin, hoʻokaʻawale like, pae maikaʻi, viscosity like, ʻōlinolino, kūpaʻa maikaʻi i ka ʻino kūlohelohe.
2. I ka hana ʻana o nā polymers e like me ka nitrile latex, butadiene, styrene, latex, a me ka styrene-acrylic latex, hiki i ka hoʻohui ʻana i kēia huahana ke hana i ka huahana resin i ka hoʻokaʻawale ʻana i ka kaumaha molekala liʻiliʻi, ka hoʻohālikelike maikaʻi ʻana o ka viscosity, i mea e hoʻopau ai ka huahana i ka polymerization e like me nā koi o ke kaʻina hana.
3. i ka hana ʻana o ka hana ʻana o ka auxilary ACR hiki ke hoʻomalu pono ʻia ka viscosity intrinsic o ka huahana.
4. ʻO ka polystyrene hopena kiʻekiʻe a me ka resin ABs e hāʻawi ana i ka hana anti-cracking maikaʻi a me ka hana mahana haʻahaʻa.
5.SAN resinvinyl polymer (vinyl polymer) kaohi i ke kaumaha molekala a me ke kūlike
Hoʻemi ka polymer 6.EVA i ka hoʻokumu ʻana o ka maka iʻa a me ka noe.
7. ʻO nā ʻāpana polymer i loaʻa mai nā EP he haiki ka nui o nā ʻāpana a me nā waiwai maikaʻi o ka ʻili. Me PEwaxHiki ke hana hou ʻia nā EPS
8. Loaʻa i ka resin styrene i hoʻololi ʻia ka Rubber ke kahe maikaʻi o ka heheʻe a me nā huahana ʻala ʻole. 5 Vinylpolymer (vinylpolymer), ka hopena polymerization suspension. @ Nā huahana PE crosslinked ma ke ʻano he mea hoʻopaʻa wela. 200 kg/pahu hao. 0.5-3% (ma ke kaumaha)
Palekana
Pono e mālama ʻia nā hana palekana maʻamau i ka wā e lawelawe ai i nā kemika. ʻO kēia mau mea nā ana i wehewehe ʻia ma nā lula olakino a me ka palekana Pekelala, Mokuʻāina a me ke kūloko, ka ea pono ʻana o ka wahi hana, ka mālama ʻili maikaʻi a me ke kau ʻana i nā goggles pale. Hāʻawi ʻia nā ʻike palekana āpau ma ka Palapala ʻIkepili Palekana no ka styrene acrylic resin.
Ka Waihona
E ʻoluʻolu e nānā i ka puke pai "Handling and Storage of Polymer Dispersions". Pono e mālama ʻia nā hana palekana maʻamau i ka wā e lawelawe ai i nā kemika. ʻO kēia mau mea nā hana i wehewehe ʻia ma nā lula olakino a me ka palekana o ka Federal, State a me Local, ka ea pono ʻana o ka wahi hana, ka mālama ʻili maikaʻi a me ke kau ʻana i nā goggles pale. Hāʻawi ʻia nā ʻike palekana āpau ma ka Palapala ʻIkepili Palekana no ka styrene acrylic resin.
