4,4′ – DIHYDROXYDIPHENYLMETHANE: Isetyenziswa kakhulu kodwa iingozi zempilo ziyaxhalabisa

Isithako sekhemikhali esisetyenziswa kakhulu kwiindawo ezininzi zoshishino nakubomi bemihla ngemihla sitsala ingqalelo engakumbi kuluntu nakuluntu lwezenzululwazi.

I. 4,4′ – DIHYDROXYDIPHENYLMETHANEineendlela ezahlukeneyo zokusetyenziswa. Kwicandelo lemizi-mveliso, i-4,4′ – DIHYDROXYDIPHENYLMETHANE sisixhobo esibalulekileyo sokwenza ii-resin ze-epoxy ezisebenza kakuhle. Olu hlobo lwe-resin ye-epoxy lusetyenziswa kakhulu kumashishini e-elektroniki kunye nezixhobo zombane. Umzekelo, kwinkqubo yokuvelisa iibhodi zesekethe eziprintiweyo (ii-PCB), ii-resin ze-epoxy zohlobo lwe-4,4′ – DIHYDROXYDIPHENYLMETHANE, ezineempawu zazo ezibalaseleyo zombane, zoomatshini kunye nokumelana nobushushu, zinokuqinisekisa ukusebenza okuzinzileyo kwezinto ze-elektroniki kwiindawo zokusebenza ezinzima. Kwishishini lokwakha, izixhobo eziqulethe i-4,4′ – DIHYDROXYDIPHENYLMETHANE nazo zidlala indima ebalulekileyo. Zisetyenziselwa ukuvelisa iingubo kunye nee-adhesives ezisebenza kakuhle, ezinokubonelela ngokuqina okuhle kunye nokunamathela, okwenza isakhiwo sesakhiwo sizinze ngakumbi kwaye ukhuseleko lwangaphandle lwesakhiwo luhlale ixesha elide. Ukongeza, i-4,4′ – DIHYDROXYDIPHENYLMETHANE ikwavela kumashishini emveliso aphezulu afana nokuvelisa iimoto kunye neenqwelo-moya. Umzekelo, ekukhuseleni iinxalenye zeemoto kunye nokubopha kwesakhiwo sezixhobo zeenqwelo-moya, i-4,4′ – DIHYDROXYDIPHENYLMETHANE inegalelo ekuphuculeni ukusebenza kwemveliso.

II. Iingozi zempilo zibangela inkxalabo. Nangona kunjalo, njengoko uphando luqhubeka lusanda, iingozi zempilo ezinokubakho ze-4,4′ – DIHYDROXYDIPHENYLMETHANE ziqalile ukuvuselela uqwalaselo lwabantu. Izifundo ezininzi zesayensi zibonise ukuba i-4,4′ – DIHYDROXYDIPHENYLMETHANE inokuba ne-endocrine – ephazamisa iipropati ezifana ne-4,4′ – DIHYDROXYDIPHENYLMETHANE (BPA). Iziphazamisi ze-endocrine zinokuphazamisa inkqubo ye-endocrine yomntu kwaye zichaphazele ukukhutshwa okuqhelekileyo kunye nemisebenzi yokulawula iihomoni. Ezinye iimvavanyo zezilwanyana zibonise ukuba izilwanyana zovavanyo ezivezwe kwindawo ye-4,4′ – DIHYDROXYDIPHENYLMETHANE zinokuba nophuhliso olungaqhelekanga lwenkqubo yokuzala, ukungasebenzi kakuhle kwe-thyroid kunye nezinye izinto. Nangona okwangoku kungekho bungqina bucacileyo kubantu, xa sijonga iingxaki zempilo ezakha zabangelwa yi-4,4′ – DIHYDROXYDIPHENYLMETHANE kunye nokufana kwizakhiwo zeekhemikhali ze-4,4′ – DIHYDROXYDIPHENYLMETHANE kunye ne-4,4′ – DIHYDROXYDIPHENYLMETHANE, le ngozi inokubakho ayinakuthathelwa ngqalelo.

III. Ulawulo kunye namanyathelo okulwa. Ngenxa yeengozi zempilo ezinokubakho ze-4,4′DIHYDROXYDIPHENYLMETHANE, amanye amazwe kunye nemimandla sele iqalile ukuyilawula. Amasebe afanelekileyo aqulunqa imigangatho engqongqo yokusingqongileyo kunye nemigangatho yokhuseleko lwemveliso ukunciphisa ukusetyenziswa kwe-4,4′ – DIHYDROXYDIPHENYLMETHANE kwezinye iimveliso ezinokuba zisondelelene nomzimba womntu. Kwicala leshishini, amanye amashishini eekhemikhali kunye namashishini asebenzisa i-application asezantsi nawo ahlola ngokukhutheleyo ezinye iindlela endaweni ye-4,4′ – DIHYDROXYDIPHENYLMETHANE, ngakumbi kwiindawo ezineemfuno eziphezulu zokhuseleko ezifana nokupakishwa kokutya kunye neemveliso zabantwana. Abasebenzi be-R & D bazama ukufumana izixhobo ezintsha ezinokuhlangabezana neemfuno zokusebenza kwemveliso ngelixa beqinisekisa ukuba zinobuhlobo kwimpilo yabantu nakwindalo esingqongileyo. 4,4′ – DIHYDROXYDIPHENYLMETHANE idlala indima ebalulekileyo kuphuhliso lwemizi-mveliso, kodwa iingozi zayo zempilo kufuneka zithathwe nzulu. Ngenxa yokwanda kophando lwesayensi kunye nokuphuculwa kancinci kancinci kweendlela zokulawula, kunethemba lokuba nangona kusetyenziswa izibonelelo zalo, ingozi enokubakho kwimpilo yabantu nakwindalo esingqongileyo ingancitshiswa.
