Izongezo ezisebenzayo
i-UV esebenzayo, i-LS esebenzayo, i-double bond reactive additive

I-resin yaseTshayina (echazwe ngokubanzi, nayiphi na i-polymer compound enokuthi isetyenziswe njengemathiriyeli ekrwada yokulungiswa kweemveliso zeplastiki ibizwa ngokuba yi-resin) ishishini likhula ngokukhawuleza.Imveliso yemveliso iyaqhubeka nokwandisa, kwaye umgaqo-nkqubo welizwe loshishino ukhuthaza imboni ye-resin ukuba iphuhlise kwicala lemveliso ye-high-tech.Ukwahluka kwe-resin yaseTshayina kuye kwagqibelela, kodwa xa kuthelekiswa nabalingane abaphambili bangaphandle, kusekho umsantsa othile kwisikali semveliso, ulawulo lwenkqubo kunye nezinye iimveliso ezineemfuno zokusebenza ezizodwa.Ngoko ke, kwiminyaka embalwa ezayo, kuphela uphando kunye nophuhliso lweemveliso eziphezulu zokusebenza, ukuphucula ukuzinza komgangatho wemveliso, yinto ephuthumayo yokuphuhliswa kwe-resin, nayo isisiseko.

Izinto ze-resin kulula ukuguga, xa zisesichengeni sokukhanya, ibhondi ephindwe kabini engaxutywanga kwisakhiwo semolekyuli okanye izinto ezingacocekanga kwinkqubo kunokwenzeka ukuba zaphule ukuwohloka kwebhondi, ukusabela kwekhonkco lasimahla, kwaye kuphembelele isizukulwana sombala. iqela, ekugqibeleni likhokelela kwi-resin fade kunye nokuqhekeka.Ukuze ucombulule ingxaki ye-photoaging ye-resin, kuyimfuneko yokongeza i-photostabilizer kwi-resin ukwenzela ukuvimbela okanye ukulibazisa inkqubo yokufota kunye nokwandisa ubomi bayo benkonzo.

I-stabilizer yokukhanya luhlobo lwe-arhente encedisayo enokuthintela okanye ukulibazisa ukuchithwa kwe-photodegradation ye-resin.Kulo lonke uphuhliso kunye nesimo sophando ekhaya nakwamanye amazwe, uphuhliso kunye nophando lwezinzisi zokukhanya lubonisa ezinye iindlela ezintsha kunye neempawu, ukufuna ngokufanelekileyo, ukhuseleko lokusingqongileyo, uqoqosho kunye nokuhlangabezana nokuphathwa kakubi kunye nokusingqongileyo kwesicelo seentlobo ezintsha zokuzinzisa ukukhanya, isakhiwo esitsha. ibisoloko iyinjongo yophuhliso lwamashishini kunye nophando.Ngokukodwa, lukhokelo olubalulekileyo lophuhliso lwezinzisi zokukhanya ukudibanisa amaqela ahlukeneyo asebenzayo kwi-molecule enye ukwenza i-molecule ibe ne-multifunctional reactivity kunye nokuphucula ukusebenza kwayo.Ngokuzisa i-chemical bond ye-monomer esebenzayo kwikhonkco yesebe le-resin okanye i-chain chain, i-stabilizer yokukhanya esebenzayo inokudlala iimpawu zamandla aphezulu kunye nokuchasana kwe-solvent kunye nokumelana nokukhanya kwe-resin, enethemba eliqinileyo lesicelo.Ukongezwa kwe-reactive light stabilizer kwi-resin akuyi kuchaphazela kakhulu isakhiwo semolekyuli ye-resin, kodwa kunokuphucula ezinye iimpawu ze-resin ngokwayo iziphene, kwaye emva koko kuphuculwe ukusebenza kunye nokusetyenziswa kwe-resin, ukuphucula ixabiso kunye nenkonzo. ubomi be-resin.

I-Reactive light stabilizer ibhekiselele ekungekweni kwamaqela asebenzayo kwisakhiwo semolekyuli ye-amine evaliweyo, ukuze idityaniswe okanye ihlonyelwe kumqolo wepolymer ngexesha lokusetyenzwa kweemveliso zepolymer ukwenza ipolymer esisigxina enokufota kunye namaqela asebenzayo e-amine avaliweyo.Oku kuzinziswa kokukhanya kunokuthintela ukufuduka komzimba okanye ukuguquguquka okubangelwa ukulahleka kokuzinzisa ukukhanya, ukuphucula nokuphucula ukusasazwa kwe-amine evaliweyo yokukhanya kwe-polymer kunye nefuthe lokuzinzisa ukukhanya, ngakumbi emva kokuphinda kusetyenziswe imveliso yepolymer kunye nokuveliswa kwakhona. , iqela lokuzinzisa ukukhanya lisenokudlala isiphumo esihle sokuzinzisa ukukhanya.Ukudibanisa ngokusisigxina kwe-amine molecule evaliweyo kwi-polymer backbone ngamaqela asebenzayo ngumlinganiselo osebenzayo wokusombulula ingxaki ye-photostability esisigxina yeemveliso zeplastiki.Iinkampani zangaphandle ezibandakanya iJapan Showa Denko, i-Adico, njl., ziye zaqalisa i-methacrylate njengeqela elisebenzayo le-ejenti yokuqinisa ukukhanya, enefuthe elingcono lokuzinzisa ukukhanya.Kodwa iqela le-methacrylate alizinzile, kwi-synthesis yesidingo sokongeza i-polymerization inhibitor ukuphepha ukwenzeka kwe-self-polymerization, ngoko ke akunakuphepheka ukwandisa ubunzima bonyango emva kokunyanga.Ukongeza, i-methacrylate yinto eguqukayo enetyhefu ephakathi, eyingozi kubaqhubi.

I-reaction light stabilizer ineengenelo ezingezantsi:
izixhobo ezikhuselekileyo ezikrwada;
ihambelana nokusingqongileyo;
i-catalyst inoqoqosho kwaye iyasebenza;
indlela yokulungiselela ilula kwaye ixabiso lezinto eziluhlaza liphantsi, elinokuthi libe ngokubanzi
isetyenziswe kwimveliso yoshishino, ukwenzela ukuphuhlisa izicelo kwiinkalo zeekhemikhali zolwazi lwe-elektroniki oluphezulu kunye ne-photoresist.
