Zeziphi iigesi ezinetyhefu ekhutshwa yilaphu le-PTFE lobushushu obuphezulu xa utshisa?

Ilaphu le-PTFE lobushushu obuphezulu lizinzile ngokumangalisayo phantsi kweemeko zokusebenza eziqhelekileyo – liyakwazi ukumelana namaqondo obushushu aqhubekayo ukuya kuthi ga kwi-260°C kunye nohambo olufutshane ukuya kwi-300°C ngaphandle kokubola. Kodwa emlilweni, xa amaqondo okushisa angaphezu kwe-400-500 ° C, izinto ziqala ukubola. Kwaye iigesi ezikhutshwayo azingomsi oqhelekileyo.

Ukuqonda ezi ngozi kubalulekile kukhuseleko lomsebenzi, ukucwangciswa kokuphendula umlilo, kunye nokukhetha okufanelekileyo kwePPE.

I-Aokai PTFE yenza amalaphu agqunywe nge-PTFE. Siluthatha nzulu ukhuseleko. Esi sikhokelo sichaza ukuba zeziphi iigesi ezikhutshwayo, ubuthi bazo, kunye nendlela yokuzikhusela kwimeko yomlilo.

Irhasi eNcincisayo yokuLethal – iHydrogen Fluoride (HF)

Xa i-PTFE itshisa, iibhondi ze-carbon-fluorine ziyaphuka. Iiathom zefluorine zidibana nehydrogen ekufuma okanye eminye imithombo ukwenza ihydrogen fluoride (HF).

Iipropati kunye nobungozi

• Irhasi engenambala enevumba elinamandla, elinukayo.

• I-corrosive kakhulu - inyibilika emanzini ukwenza i-hydrofluoric acid.

• Icaphukisa kakhulu kwaye yonakalisa indlela yokuphefumla, ulusu kunye namehlo.

• Inokubangela i-pulmonary edema (ulwelo emiphungeni) kwiimeko ezinzima.

• I-HF ngoyena nobangela uphambili wokubhubha kwabantu abavela kwi-PTFE yokuphefumla umlilo.

Qaphela: I-HF ayinayo ityhefu kuphela ngokuphefumla - ukudibana nolusu olumanzi okanye amehlo kunokubangela ukutshisa okunzulu, okuphilisa ngokucothayo. Kwanogxininiso oluphantsi luyingozi.

Umbulali Othuleyo-Perfluoroisobutylene (PFIB)

Iyingozi ngakumbi kune-HF, kodwa engaziwa kakhulu, yi- perfluoroisobutylene (PFIB).

Iipropati kunye nobungozi

• Ayinambala kwaye ayinavumba - awukwazi ukuyivumba.

• Irhasi eyityhefu kakhulu eveliswa ngokuthe ngqo kukutsha kwefluoropolymer.

• Ubuthi bumalunga ne-10 amaxesha e-phosgene (i-agent yemfazwe yekhemikhali esetyenziswa kwi-WWI).

• Ukuphefumla kuyonakalisa i-alveoli yemiphunga, kubangela ukulibaziseka okukhulu kwe-pulmonary edema - iimpawu zisenokungabonakali iiyure.

• Akukho nyango lusebenzayo lukhoyo. Unyango luxhasayo (ioksijini, umoya wokungena ngomatshini).

Isilumkiso esibalulekileyo: Ngenxa yokuba iPFIB ayinavumba kwaye iimpawu zilibazisekile, abasebenzi banokungaqondi ukuba baye bavezwa de kube ziiyure kamva, xa kuvela uxinzelelo olukhulu lokuphefumla. Oku kwenza ukuba iPFIB ibe nenkohliso.

Ezinye iiGasi ezinetyhefu kunye neeNtsholongwane

Ukongeza kwi-HF kunye ne-PFIB, umsi womlilo we-PTFE uqulethe ezinye izinto ezinobungozi:

• I-Carbon monoxide (CO) - ukusuka ekutshisweni okungaphelelanga kwayo nayiphi na into ephilayo. Ayinambala, ayinavumba, ibophelela kwihemoglobin.

• Amalungu amahle ane-fluorine -anokuphefumlelwa nzulu emiphungeni.

• Iintsalela zePerfluorooctanoic acid (PFOA) – iintsalela ze-surfactants ezisuka kwi-PTFE zisenokukhupha umsi onetyhefu kumaqondo obushushu aphezulu (nangona i-PTFE yale mihla yehlise iPFOA).

• Landela i-dioxins – xa i-PTFE itshisa kunye nezinto ezineklorin (umzekelo, iintambo ze-PVC, ii-coatings ezithile), ii-dienzo-dioxins ezine-polychlorinated kunye neefurani zinokuveliswa.

Izilumkiso zoKhuseleko-Yintoni omawuyenze kuMlilo we-PTFE

1. Phuma kuqala. Emva koko ukhusele abaphenduli.

Ukuba ilaphu le-PTFE elinobushushu obuphezulu libamba umlilo, elona nyathelo libalulekileyo kukuphepha ukuphefumla umsi . Phuma kuloo ndawo ngoko nangoko.

2. I-PPE efanelekileyo - iimaski eziqhelekileyo zomsi azinamsebenzi

• Okufunekayo: Izixhobo zokuphefumla ezizimeleyo (SCBA) ezinobuso obugcweleyo, obukwazi ukuhluza iigesi ezimuncu kunye nokubonelela ngomoya ococekileyo.

• Kutheni ingeyiyo imaski eqhelekileyo: I -N95 eqhelekileyo okanye iimaski zotyando aziyeki i-HF, iPFIB, okanye iinxalenye ezintle. Neziphefumlo zeekhemikhali zekhatriji zisenokunganelanga kwi-PFIB.

• Ukukhuselwa kwesikhumba: Sebenzisa iimpahla ezigcweleyo ezikhusela umzimba kunye neeglavu - i-HF inokungena kwizinto eziqhelekileyo.

3. Uncedo lokuqala kunye nempendulo yonyango

• Ukuba umsi uphefumle ngempazamo, khawuleza uye kumoya omtsha.

• Funa unyango olungxamisekileyo - musa ukulinda iimpawu.

• Kubalulekile: Iimpawu ezihambelanayo (ingakumbi kwi-PFIB) zinokuba nokulibaziseka kokuqala ukuya kwiiyure ze-24. Nokuba umntu uziva ephilile ekuqaleni, kufuneka avavanywe ngugqirha.

• Yazisa abasebenzi bezonyango ukuba isigulane sibonakaliswe kwiimveliso zokutsha ze-PTFE - i-HF kunye ne-PFIB yetyhefu ifuna ukunakekelwa okuthe ngqo kwenkxaso.

Isiteyitimenti sokhuseleko se-Aokai PTFE: Ilaphu le-PTFE likhuselekile kusetyenziso oluqhelekileyo kunye nokutshisa ngokufutshane ngaphandle kokubola. Kufuneka umlilo ukuvelisa ezi gesi. Nangona kunjalo, izicwangciso zokhuseleko lomlilo kumaziko asebenzisa izinto ze-PTFE kufuneka zibandakanye izixhobo ze-SCBA kunye noqeqesho kwiimpawu zokulibaziseka.

Isishwankathelo – Yazi imingcipheko, Cwangcisa Ngokufanelekileyo

Izinto eziphambili ezithathwayo:

• Ilaphu le-PTFE likhuselekile phantsi kokusetyenziswa kwesiqhelo – aliboli ngaphantsi kwe-300°C.

• Emlilweni, ikhupha ihydrogen fluoride kunye neperfluoroisobutylene (PFIB), zombini zinetyhefu kakhulu.

• I-PFIB iyingozi kakhulu - ayinavumba, akukho antidote, iimpawu zilibazisekile.

• Ungaze usebenzise iimaski eziqhelekileyo zomsi. I-SCBA iyafuneka.

• Emva kokuba sesichengeni, funa uvavanyo lonyango nokuba akukho zimpawu zikhawulezayo.

I-Aokai PTFE ibonelela ngamaxwebhu edatha yokhuseleko (SDS) kuzo zonke iimveliso zelaphu ze-PTFE. Sicebisa ukuba abathengi baphonononge iiprothokholi zokuphendula umlilo kunye namaqela abo okhuseleko.

Olu lwazi lungentla lunikezelwa ngu I-Jiangsu Aokai yeZixhobo eziNtsha zeTekhnoloji Co., Ltd.
