Mea Hoʻopaʻa Mālamalama-944 CAS 70624-18-9
He kūpaʻa maikaʻi ka mea hoʻopaʻa kukui UV-944 i ka hoʻohemo ʻana, kūpono loa no nā huahana lahilahi, e like me nā olonā a me nā kiʻiʻoniʻoni; Hiki iā ia ke hoʻomaikaʻi i ke kūpaʻa ʻelemakule oxygen wela o ka mea. ʻO ka mea hoʻopaʻa kukui HS-944 he keʻokeʻo a i ʻole nā mea melemele māmā a i ʻole ka pauka, kahi heheʻe 100-135°C, ke kaumaha molekala 2000-3100, me ka hoʻohālikelike maikaʻi loa, ke kūpaʻa hoʻohemo a me ka haʻahaʻa haʻahaʻa. ʻOiai ʻo UV-944 kahi mea hoʻopaʻa nui molekala pili kiʻekiʻe, a loaʻa i ka molekala kahi nui o ka methylate, paʻa ia i ka wā e mālama ʻia me ka oxygen wela.

Hoʻohana ʻia ka Light Stabilizer-944 i loko o ka ʻili polyethylene haʻahaʻa haʻahaʻa, ka polypropylene fiber, ka polypropylene tape, ka EVA film, ABS, polystyrene a me nā ʻōpala meaʻai. No ka mea hoʻopaʻa māmā ʻo HS-944 ka mea hoʻopaʻa māmā amine hindered.
1. Ka hopena hoʻopaʻa kukui maikaʻi loa: Hiki i ka UV-944 ke pale pono i nā mea polymer mai ka ʻike ʻana o ka kukui ultraviolet a me ka photodegradation a me ka hoʻohaʻahaʻa wela i hoʻokumu ʻia e ka ʻelemakule wela lōʻihi. ʻOi aku ka hopena o kona hoʻopaʻa kukui ma mua o nā mea hoʻomoʻa ultraviolet a me nā mea hoʻopaʻa nickel, ʻoi aku hoʻi i nā ʻōnaehana pigment kahi i ʻike nui ʻia ai ka hopena.
2. Hoʻohālikelike maikaʻi a me ka hana hana: He mea granular melemele māmā me ka volatility haʻahaʻa. Loaʻa iā ia ka hoʻohālikelike maikaʻi me nā mea polymer like ʻole e like me PP, LDPE, HDPE, a me PVC. Hiki ke hoʻopuehu maʻalahi ʻia i loko o ka matrix polymer me ka ʻole o ka hoʻopilikia ʻana i ka transparency a me ke kala o ka resin, a he hana hana maikaʻi loa.
3. Ka laulā o ka hoʻohana ʻana a palekana a hilinaʻi hoʻi: He kūpono ʻo UV-944 no nā ʻano mea like ʻole e like me nā kiʻiʻoniʻoni, nā olonā, a me nā huahana mānoanoa, a hiki ke hoʻohana ʻia no nā polymers he nui e like me nā polyolefins, polyurethanes, a me nā polyamides. I kēia manawa, ua ʻae ʻia e ka FDA a hiki ke hoʻohana ʻia i nā noi pili meaʻai, e hōʻike ana i kahi pae palekana.
25kg/pahu a e like me nā koi a ka mea kūʻai aku.
