Ngexesha leholide yoMnyhadala weNtwasahlobo, uninzi lweefektri ze-epoxy resin e-China zikwimo yokuvalwa ukuze zigcinwe, kunye nesantya sokusetyenziswa kwamandla malunga ne-30%. Amashishini etheminali asezantsi kakhulu akwimeko yokucinywa kunye neholide, kwaye okwangoku akukho mfuno yokuthenga. Kulindeleke ukuba emva kweholide, ezinye iimfuno ezibalulekileyo ziya kuxhasa ugqaliselo oluqinileyo lwemarike, kodwa uzinzo lulinganiselwe.

1. Uhlalutyo lweendleko:

1. Intsingiselo yentengiso ye-bisphenol A: Imarike ye-bisphenol A ibonisa ukuguquguquka okumxinwa, ngenxa yozinzo lonikezelo lwemathiriyeli ekrwada kunye necala lemfuno elizinzileyo. Nangona utshintsho kumaxabiso e-oyile ekrwada kumazwe ngamazwe lunokuba nefuthe elithile kwiindleko ze-bisphenol A, kuqwalaselwa uluhlu olubanzi losetyenziso, ixabiso layo alichatshazelwa kangako yinto enye ekrwada.

2. Uguqulo lwentengiso ye-epichlorohydrin: Imakethi ye-epichlorohydrin inokubonisa umkhwa wokunyuka kokuqala kunye nokuwa. Oku kubangelwe ikakhulu kukuchacha ngokuthe ngcembe kwemfuno ephantsi komlambo emva kweholide kunye nokufunyanwa kwakhona kwezothutho. Nangona kunjalo, njengoko unikezelo lukhula kwaye imfuno iya kuzinza ngokuthe ngcembe, amaxabiso anokufumana ukutsalwa.

3. Uqikelelo lwendlela ye-oyile ekrwada kumazwe ngamazwe: Kusenokubakho indawo yokunyuka kwamaxabiso e-oyile kumazwe ngamazwe emva kweholide, echatshazelwa ikakhulu kukuncitshiswa kwemveliso ye-OPEC, ukungavisisani ngokwelizwe kuMbindi Mpuma, kunye nokulungiswa okunyukayo koqikelelo lokukhula koqoqosho lwehlabathi. Oku kuya kubonelela ngenkxaso yeendleko zemathiriyeli ekrwada enyukayo ye-epoxy resin.

2. Uhlalutyo lwecala lonikezelo:

1. Umthamo wokusetyenziswa kwesityalo se-epoxy resin: Ngexesha loMthendeleko weNtwasahlobo, uninzi lweeyunithi zezityalo ze-epoxy resin zavalwa ukuze zigcinwe, okubangele ukuhla okubonakalayo kwireyithi yokusetyenziswa kwamandla. Oku ikakhulu sisicwangciso esamkelwe ngamashishini ukugcina ibhalansi yemfuno yonikezelo kwimarike yasemva kweholide.

2. Isicwangciso esitsha sokukhutshwa kwamandla: NgoFebruwari, okwangoku akukho sicwangciso esitsha sokukhupha umthamo kwimarike ye-epoxy resin. Oku kuthetha ukuba ukubonelela kwiimarike kuya kulinganiselwa kwixesha elifutshane, elinokuthi libe nefuthe elithile elixhasayo kumaxabiso.

3.Imeko yokulandelelwa kwemfuno yeterminal: Emva kweholide, imizi-mveliso esezantsi efana neecoatings, amandla omoya, kunye ne-electronics kunye nobunjineli bombane banokuthi baphinde bazalise imfuno ngezigaba. Oku kuya kubonelela ngenkxaso yemfuno ethile kwimarike ye-epoxy resin.

3. Uqikelelo lwentsingiselo yemarike:

Uthathela ingqalelo zombini iindleko kunye nokubonelela ngezinto, kulindeleke ukuba imarike ye-epoxy resin inokufumana umkhwa wokunyuka kuqala kwaye wehle emva kweholide. Ngexesha elifutshane, ukuzaliswa kwemfuno kumashishini asezantsi kunye nokunyuka okuncinci kumashishini emveliso kunokunyusa amaxabiso emarike. Nangona kunjalo, njengoko ukuzaliswa kwakhona ngezigaba kuphelisa kwaye unikezelo lukhula ngokuthe ngcembe, imakethi inokuphinda iphinde ifumane ingqiqo kwaye amaxabiso anokufumana ukulungiswa.
