Nā Pōmaikaʻi o MCA:
- ʻAʻawa haʻahaʻa a me ka pala haʻahaʻa.
ʻOi aku ka nui o ka LD50 o ka melamine cyanurate ma mua o 4000 mg/kg. Ke hoʻohālikelike ʻia me ka ʻōnaehana pale lapalapa X-Sb, ʻoi aku ka haʻahaʻa o ka pala o MCA. No ka laʻana, ʻo PA66 e loaʻa ana ka MCA, i ke kūlana heheʻe (300 °C) a me ka hoʻopili ʻana me ke kila kila ma hope o 100 h, ʻo ka ʻōnaehana MCA ma ka pala o ka ʻōmole kila kila, 1/50 wale nō o ka ʻōnaehana X-Sb.
- Haʻahaʻa ka nui o ka uahi i hana ʻia.
Hoʻokuʻu ʻo MCA i ka CO2, N2 a me NH3 i ka wā e palaho ai ka wela, a ʻaʻohe HX i hana ʻia, no laila ʻo ka nui o ka uahi a me nā huahana ʻawahia a me nā huahana corrosive i hana ʻia i ka wā o ka haki ʻana a me ke kuni ʻana o ka wela he haʻahaʻa loa ia. No ka laʻana, ʻo ka nui o ka uahi (Dm) o ka PA6 i hoʻoikaika ʻole ʻia (UL94 V-0), ka mea e pale aku i ka lapalapa me MCA, he 190 a me 80 i ka wā e ana ʻia ai e ka pahu uahi NITS (NBS). No PA6 (UL94 V-0), ka mea e pale aku i ka lapalapa me ka ʻōnaehana X-Sb, ʻo kēia mau waiwai ʻelua he 790 a me 390, ʻo ia hoʻi, ʻo ka mea mua ma kahi o 1/4 o ka mea hope.
(3) Ke kūpaʻa wela kiʻekiʻe Hiki iā MCA ke kū i nā mahana kiʻekiʻe ma luna o 320°C. No laila, hiki iā ia ke kū i nā mahana hana o nā plastik hana maʻamau.
Nā hoʻohana o ka melamine cyanurate
- Kāpae ahi
He nui ka nui o nā ʻātoma naikokene i loko o ka molekala o MCA a kūpono loa ia no ka hoʻohana ʻana ma ke ʻano he mea pale lapalapa. Eia nā hiʻohiʻona o nā noi.
(1) Hoʻohana ʻia ʻo MCA ma ke ʻano he mea pale ahi e hoʻomākaukau ai i nā hui pale ahi PA-6. Hoʻohana nui ʻia ʻo MCA i loko o ka PA i hoʻoikaika ʻole ʻia, a e like me nā helu helu, kokoke i ka 40% o ka PA pale ahi i hoʻoikaika ʻole ʻia i hoʻohana ʻia i nā plastik uila a me nā mea uila ma ʻEulopa Komohana he mau huahana pale ahi MCA i ka makahiki 2003.
ʻO ka magnesium hydroxide (MH) inorganic flame retardant inorganic a me ka nitrogen-based flame retardant melamine cyanurate nā mea hoʻolohi lapalapa halogen-free i hoʻohana pinepine ʻia no PA6 i kēia manawa. Ua hōʻike ʻia nā haʻawina e hoʻohana ʻia ʻo MCA a me MH ma ke ʻano he mau mea hoʻolohi lapalapa e hoʻomākaukau ai i nā composites flame retardant PA6. I ka wā he 20 mau ʻāpana ka nui o MCA a me MH, hiki i ka helu oxygen hope loa o ka composite PA6/MCA ke hōʻea i 30.5, ʻoiai ʻo ka helu oxygen hope loa o ka composite PA6/MH he 23.5 wale nō, e hōʻike ana ua kiʻekiʻe ka pono o ka MCA no ka hoʻolohi lapalapa.
I kēia manawa, ʻo ka ikaika tensile o ka hui PA6/MCA he 66.8 MPa, 1.14 manawa o ka hui PA6/MH. ʻO ka nui o ke kahe heheʻe o ka hui PA6/MCA i hōʻea i 74 g/10 min, 4.9 manawa o ka hui PA6/MH.
(2) ʻO MCA ma ke ʻano he mea pale ahi no nā resins epoxy. Hiki i ka MCA ma ke ʻano he mea pale ahi ke hoʻonui i ka helu oxygen o ka resin epoxy mai 24-28 a i 46-48. Hōʻike ka noiʻi he hopena pale ahi maikaʻi loa ka MCA ma ka hui hoʻōla anhydride resin epoxy (EP), i ka wā he 5 mau ʻāpana wale nō ka dosage hiki iā EP ke hōʻea i ke kiʻekiʻe o ka hoʻopau ponoʻī ʻana.
Ua hoʻemi ʻo MCA i ka mahana hoʻoheheʻe hoʻomaka wela a me ka nui o ka pohō kaumaha wela o EP, a hoʻomaikaʻi i ke kūpaʻa wela o EP i nā mahana kiʻekiʻe.
(3) Hiki ke hoʻohui ʻia ʻo MCA i nā emulsions vinyl acetate, nā emulsions acrylate a me nā emulsions rubber e hana i nā uhi flame retardant. Hōʻike ka noiʻi he maikaʻi loa ka hoʻopili ʻana o ka ʻili uhi a me ka laumania, a ʻaʻohe haumia kala.
(4) PBT pale ahi. 100 ʻāpana o PBT, 5 ʻāpana o ka mica synthetic fluorinated, 5 ʻāpana o MCA, hana pale ahi a hiki i ka pae UL94V-0. He ākea ka laulā o ka noi pale ahi MCA, hiki ke hoʻohana ʻia i loko o polyamide 6 (66), PET (polyethylene terephthalate), TPE (thermoplastic elastomer cable), PU (polyurethane), POM (polyformaldehyde), PET (polyethylene terephthalate), phenolic resin, epoxy resin, PTFE (polytetrafluoroethylene) resin, acrylic emulsion, PPO / PS a me nā mea ʻē aʻe.
- Nā mea hoʻohui lubricant
MCA can be formulated as a water-based lubricant and as an additive to solid lubricants and lubricating oils, with obvious oil-saving effects. It can be widely used in various mechanical lubrication under high temperature, low temperature and high pressure conditions, and has excellent wear resistance. As a lubricant, MCA has many properties similar to those of the solid lubricant molybdenum disulphide, but at a much lower price than molybdenum disulphide, making it an ideal substitute. The product is white and is described as odourless and easy to clean; safety properties depend on the specific formulation and SDS, so it has the advantage of preventing pollution and colouring in the lubrication of video, household chemicals, sewing and packaging machinery.
- Other hoʻohana
(1) Mea hoʻopili kemika fiber no nā uhi.
He maikaʻi ka hoʻopili ʻana o MCA a me ka resin, ʻaʻole maʻalahi e hāʻule, akā ʻaʻole hoʻi e maʻalahi ke hoʻohaumia, a ʻoi aku ka maikaʻi o ka hoʻohana ʻana ma ke ʻano he mea hoʻohuihui kemika ma mua o Chinbai a me ka silica gel.
- Nā mea hoʻohui plastik papa plating.
ʻO MCA ma ke ʻano he mea hoʻohui i komo i loko o ka plastic nylon, hiki ke hoʻonui i ka hoʻopili ʻana i ka wā e uhi ai. I ka wā ma mua, ʻaʻole i hoʻokō ka ikaika hoʻopili ma waena o ka plastic a me ka uhi metala i nā koi a ua kaupalena ʻia i ka uhi ʻana o ABS, ʻoiai ʻaʻole maʻalahi ka plastic nylon e uhi. I kēia mau lā, ʻo ka hoʻohui ʻana o MCA i ka nylon e hāʻawi i ka hoʻopili interlayer maikaʻi loa ma hope o ka uhi ʻana. Hiki ke hoʻohana nui ʻia kēia plastic i uhi ʻia i nā mea pono e pale aku i ka wela, nā pūpū huʻa, nā mea huki puka, a pēlā aku.
- Nā mea hoʻohui sima polymer.
Hiki i ka hoʻohui ʻana o MCA ke hoʻomaikaʻi i ka ikaika o ka sima a hoʻolōʻihi i ke ola lawelawe o ka sima.
- Nā mea hoʻonani ʻili.
ʻOiai ʻo MCA ke kuleana o ka pale ʻana i nā hana physiological a me ka pale ʻana i ka ʻili, hiki ke hoʻohana ʻia e like me ka ʻōmaʻomaʻo kahi, ka pauka sunscreen, a pēlā aku. ʻO nā mea hoʻonani maʻamau i hoʻopili ʻia i ka ʻili, ʻo ka hapa nui ma muli o ka hou, ka waimaka, ka sebum a me nā mea huna ʻē aʻe o ke kanaka, a me ka ua, ka hau, ka wai kai a me nā wai ʻē aʻe i hoʻokumu ʻia e ke kuleana o ka denaturation, detachment, a pēlā e hōʻemi nui ai i ka hopena o ka mālama ʻili. ʻO MCA, ma ka ʻaoʻao ʻē aʻe, pili maikaʻi a he ʻano pahee a pahee hoʻi i ka ʻili, no laila he mea hoʻohui hoʻonani maikaʻi loa ia. Ke hoʻohui ʻia, hiki iā ia ke hoʻomaikaʻi nui i ka hoʻopili ʻana i ka ʻili, e hana ana i ka ʻili maikaʻi, paʻa a laumania.
No ka ʻike hou aku a i ʻole nā laʻana manuahi a i ʻole nā kumukūʻai, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou ma o ka leka uila: [email protected] , a i ʻole e kelepona mai iā mākou ma: +86-28-8411-1861.
Hoʻopuka hou ʻia kekahi mau kiʻi a me nā kikokikona mai ka Pūnaewele, a no ka mea kākau kumu ke kuleana kope. Inā loaʻa kekahi hewa, e ʻoluʻolu e kelepona mai iā mākou e holoi.
