Izinzuzo ze-MCA:
- Ubuthi obuphansi kanye nokugqwala okuphansi.
I-LD50 ye -melamine cyanurate inkulu kune-4000 mg/kg. Uma kuqhathaniswa nohlelo lwe-X-Sb oluvimbela ilangabi, ukugqwala kwe-MCA kuphansi kakhulu. Isibonelo, i-PA66 equkethe i-MCA, esimweni esincibilikisiwe (300 °C) kanye nokuxhumana kwensimbi engagqwali ngemva kwamahora ayi-100, uhlelo lwe-MCA ekugqwaleni kwesikhunta sensimbi engagqwali, yi-1/50 kuphela yohlelo lwe-X-Sb.
- Inani lentuthu ekhiqizwayo liphansi.
I-MCA ikhipha i-CO2, i-N2 ne-NH3 lapho ibola ngokushisa, futhi ayikho i-HX ekhiqizwayo, ngakho-ke inani lentuthu nemikhiqizo enobuthi negqwalayo ekhiqizwa ngesikhathi sokuqhekeka okushisayo kanye nokusha liphansi kakhulu. Isibonelo, ubuningi bokuminyana kwentuthu (Dm) ye-PA6 engaqinisiwe (UL94 V-0), ene-flame-retardant nge-MCA, ingu-190 kanye no-80 ngokulandelanayo uma ikalwa ngebhokisi lentuthu le-NITS (NBS). Ku-PA6 (UL94 V-0), ene-flame retardant ngohlelo lwe-X-Sb, lawa manani amabili aphakeme njengo-790 no-390 ngokulandelana, okusho ukuthi owangaphambili cishe u-1/4 wakamuva.
(3) Ukuzinza okuphezulu kwe-thermal MCA iyakwazi ukumelana nezinga lokushisa elingaphezu kuka-320°C. Ngakho-ke, ingakwazi ukumelana namazinga okushisa okucutshungulwa kwamapulastiki enhloso evamile.
Ukusetshenziswa kwe-melamine cyanrate
- I-flame retardant
I-MCA inenani elibalulekile lama-athomu e-nitrogen ku-molecule futhi ifaneleka ngokukhethekile ukusetshenziswa njengesinqamuleli somlilo. Izibonelo zezicelo zimi kanje.
(1) I-MCA isetshenziswa njengesinqamuleli somlilo ukuze kulungiswe izinhlanganisela ze-PA-6 ze-flame retardant. I-MCA isetshenziswa kakhulu ku-PA engaqinisiwe, futhi ngokwezibalo, cishe amaphesenti angama-40 e-PA engaqinisiwe ye-flame retardant esetshenziswa kumapulasitiki kagesi nawe-elekthronikhi eNtshonalanga Yurophu kwakuyimikhiqizo ye-MCA ye-flame retardant ngo-2003.
I-Inorganic flame retardant magnesium hydroxide (MH) kanye ne-nitrogen-based flame retardant melamine cynurate zivame ukusetshenziswa ezibushela ilangabi ezingenalo halogen ze-PA6 okwamanje. Ucwaningo luye lwabonisa ukuthi i-MCA ne-MH zisetshenziswa njengezinqamuli zomlilo ukuze kulungiswe izinhlanganisela ze-PA6 flame retardant ngokulandelanayo. Lapho umthamo we-MCA ne-MH wawuyizingxenye ze-20, inkomba yokugcina ye-oksijeni ye-PA6/MCA eyinhlanganisela ingafinyelela ku-30.5, kuyilapho inkomba yokugcina ye-oxygen ye-PA6/MH ehlanganisiwe yayiyi-23.5 kuphela, ebonisa ukuthi ukusebenza kahle komlilo we-MCA kwakuphakeme.
Phakathi naleso sikhathi, amandla aqinile we-PA6/MCA ehlanganisiwe ayengu-66.8 MPa, izikhathi ezingu-1.14 kunawe-PA6/MH eyinhlanganisela. Izinga lokuncibilika lokuncibilika kwenhlanganisela ye-PA6/MCA lifinyelele ku-74 g/10 min, 4. 9 izikhathi lapho lenhlanganisela ye-PA6/MH.
(2) I-MCA njenge-flame retardant yama-epoxy resins. I-MCA njenge-flame retardant ingakhuphula inkomba ye-oxygen ye-epoxy resin isuka ku-24-28 iye ku-46-48. Ucwaningo lubonisa ukuthi i-MCA inomphumela omuhle kakhulu we-flame retardant ku-epoxy resin anhydride curing compound (EP), lapho umthamo uyizingxenye ezi-5 kuphela ezingenza i-EP ifinyelele izinga lokuzicisha.
I-MCA yehlise izinga lokushisa lokubola kokuqala okushisayo kanye nezinga eliphezulu lokulahlekelwa kwesisindo esishisayo se-EP, futhi yathuthukisa ukuzinza okushisayo kwe-EP emazingeni okushisa aphezulu.
(3) I-MCA ingangezwa kuma-emulsions e-vinyl acetate, ama-emulsions e-acrylate kanye nama-emulsions enjoloba ukwenza ama-flame retardant coatings. Ucwaningo lubonisa ukuthi ukunamathela kwefilimu enamathelayo nokushelela kuhle kakhulu, futhi akukho ukungcoliswa kombala.
(4) I-PBT ye-flame retardant. Izingxenye ezingu-100 ze-PBT, izingxenye ezingu-5 ze-mica yokwenziwa e-fluorinated, izingxenye ezingu-5 ze-MCA, ukusebenza kwe-flame retardant kufika kuleveli ye-UL94V-0. Ibanga lesicelo le-MCA le-flame retardant libanzi uma kuqhathaniswa, lingasetshenziswa ku-polyamide 6 (66), i-PET (i-polyethylene terephthalate), i-TPE (ikhebula le-thermoplastic elastomer), i-PU (i-polyurethane), i-POM (i-polyformaldehyde), i-PET (i-polyethylene terephthalate), i-phenolic resin, i-epoxyneflupolyethy emulsion acrylic, PPO / PS nezinye izinto.
- Izithasiselo zokuthambisa
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.
- Okunye kusebenzisa
(1) I-ejenti yokubopha i-fiber yamakhemikhali yokumboza.
I-MCA kanye ne-resin adhesion kuhle, akulula ukuwa, kodwa futhi akulula ukudala ukungcola, isetshenziswa njengomphumela we-chemical fiber matting agent kune-Chinbai nejeli ye-silica ingcono.
- Plating grade izithasiselo zepulasitiki.
I-MCA njengesithasiselo esingeniswa kupulasitiki enayiloni, ingathuthukisa ukunamathela lapho icwecwa. Esikhathini esedlule, amandla okunamathela phakathi kwepulasitiki nensimbi enamathelayo awazange ahlangabezane nezidingo futhi akhawulelwe ekucwecweni kwe-ABS, kanti ipulasitiki yenayiloni akulula ukuyihlanganisa. Namuhla, ukungezwa kwe-MCA kunayiloni kunikeza ukunamathela okuhle kakhulu kwe-interlayer ngemuva kokucwenga. Le plastic plated ingasetshenziswa kabanzi ezinsizakalweni ezingashisi ukushisa, amagobolondo egwebu, ukudonsa kweminyango, njll.
- Izithasiselo zikakhonkolo ze-polymer.
Ukwengeza i-MCA kungathuthukisa amandla kakhonkolo futhi kunwebe impilo yesevisi kakhonkolo.
- Impahla eluhlaza yezimonyo zesikhumba.
Njengoba i-MCA inendima yokungaphuli imisebenzi ye-physiological kanye nokuvikela isikhumba, ingasetshenziswa njengokushefa okuluhlaza, i-sunscreen powder, njll. Izimonyo ezivamile ezisetshenziswa esikhumbeni, ikakhulukazi ngenxa yokujuluka, izinyembezi, i-sebum nezinye izimfihlo zabantu, kanye nemvula, iqhwa, amanzi olwandle kanye nolunye uketshezi olubangelwa indima ye-denaturation, ukunciphisa umphumela wokunakekelwa kwesikhumba kakhulu. I-MCA, ngakolunye uhlangothi, ibambelela kahle futhi inomuzwa ominyene, oshelelayo esikhumbeni, ngakho-ke iyisengezo sezimonyo esihle kakhulu. Uma ingeziwe, ingathuthukisa kakhulu ukunamathela esikhumbeni, yenze isikhumba sibe sihle, siminyene futhi sibushelelezi.
