Ziziphi iimpembelelo ze-fiberglass kumzimba womntu?

Ngenxa yobume bemicu yeglasi, iyaqhekeka ibe ngamaqhekeza amafutshane. Ngokutsho kovavanyo lwexesha elide olwenziwa nguMbutho wezeMpilo weHlabathi kunye neminye imibutho, iifiber ezinobubanzi obungaphantsi kwe-3 microns kunye ne-aspect ratio engaphezulu kwe-5: 1 inokuphefumlelwa nzulu kwimiphunga yomntu. Iintsinga zeglasi esiqhele ukuzisebenzisa zikhulu kune-3 ye-microns ububanzi, ngoko akukho mfuneko yakuzikhathaza ngokugqithisileyo ngeengozi zemiphunga.

Izifundo zokuchithwa kwe-in vivo zeimicu yeglasibaye babonisa ukuba i-microcracks ekhoyo kumphezulu wemicu yeglasi ngexesha lokucutshungulwa iya kwanda kwaye inzulu phantsi kohlaselo lwe-alkaline emiphunga ebuthathaka, ukwandisa indawo yabo kunye nokunciphisa amandla emicu yeglasi, ngaloo ndlela ikhawuleza ukuthotywa kwayo. Uphononongo lubonise ukuba imicu yeglasi inyibilika ngokupheleleyo kwimiphunga kwiinyanga ezi-1.2 ukuya kwezi-3.

Ngokwamaphepha ophando angaphambili, ukuvezwa kwexesha elide (ngaphezulu konyaka omnye kuzo zombini iimeko) zeempuku kunye neempuku emoyeni eziqulethe ugxininiso oluphezulu lwemicu yeglasi (ngaphezu kwekhulu leemitha kwindawo yokuvelisa) kwakungekho mpembelelo ibalulekileyo kwi-lung fibrosis okanye kwi-tumor izehlo, kwaye kuphela ukufakelwa kwemicu yeglasi ngaphakathi kwipleura yezilwanyana kutyhile i-fibrosis kwimiphunga. Uphando lwethu lwezempilo lwabasebenzi kwishishini le-fiber yeglasi ekuthethwa ngalo aluzange lufumane ukwanda okubonakalayo kwi-pneumoconiosis, umhlaza wemiphunga, okanye i-pulmonary fibrosis, kodwa yafumanisa ukuba umsebenzi wemiphunga wabasebenzi abathethiweyo uncitshisiwe xa kuthelekiswa noluntu ngokubanzi.

Nangonaimicu yeglasingokwabo azibeki ingozi ebomini, ukudibana ngokuthe ngqo kwimicu yeglasi kunokubangela imvakalelo enamandla yokucaphuka ulusu kunye namehlo, kunye nokuphefumla amasuntswana othuli aqulethe imicu yeglasi kunokucaphukisa imigudu yeempumlo, uqhoqhoqho, kunye nomqala. Iimpawu zokucaphuka zidla ngokungangqalanga kwaye zezexeshana kwaye zinokubandakanya ukurhawuzelelwa, ukukhohlela okanye ukuphefumla. Ukuvezwa okubonakalayo kwi-fiberglass yomoya kunokubangela i-asthma ekhoyo okanye iimeko ezinjenge-bronchitis. Ngokuqhelekileyo, iimpawu ezinxulumene nazo ziyancipha ngokwazo xa umntu oveziweyo ehambela kude nomthomboi-fiberglassixesha elithile.
