Lungiselela isicwangciso sokuphendula ngexesha likaxakeka ngokweempawu ezithile zotywala bepropargyl:
I. Iimpawu zotywala bepropargyl: umphunga kunye nomoya walo unokwenza umxube oqhumayo, onokubangela ukutsha kunye nokuqhuma kwimeko yomlilo ovulekileyo kunye nobushushu obuphezulu.Inokusabela nge-oxidant.Ubushushu bukhupha umsi otshisayo.Ukusabela nge-oxidant kunye ne-phosphorus pentoxide.Kulula ukuzenzela i-polymerize kwaye i-polymerization reaction iyanda ngokunyuka kwamaqondo obushushu.Umphunga wayo unzima kunomoya, kwaye unokusasazeka ukuya kumgama omde kwindawo esezantsi.Iya kubamba umlilo ize itshise kwakhona xa kuvela umthombo womlilo.Kwimeko yokushisa okukhulu, uxinzelelo lwangaphakathi lwenqanawa luya kwanda, kwaye kukho umngcipheko wokuqhaqha kunye nokuqhuma.
II.Iikhompawundi ezingavumelekanga: i-oxidants eqinile, i-acids eqinile, iziseko ezinamandla, i-acyl chlorides kunye ne-anhydrides.I-3, Indlela yokucima umlilo: Abacimi bomlilo kufuneka banxibe iimaski zegesi yokucoca (iimaski zobuso obugcweleyo) okanye iziphefumli zokuzihlukanisa, banxibe umlilo ogcweleyo womzimba kunye nempahla yokukhusela igesi, kwaye bacime umlilo kwicala elinomoya.Susa isikhongozeli ukusuka kwindawo yomlilo usise kwindawo evulekileyo kangangoko unako.Tshiza amanzi ukugcina izikhongozeli kwindawo yomlilo zipholile de kugqitywe ukucima umlilo.Izikhongozeli kwindawo yomlilo kufuneka zikhutshwe ngokukhawuleza ukuba zitshintshile umbala okanye zivelise isandi kwisixhobo sokunciphisa uxinzelelo lokhuseleko.Into yokucima umlilo: amanzi anenkungu, ugwebu, umgubo owomileyo, ikharbon diokside, isanti.
IV.imiqathango yogcino nothutho: gcina kwindawo epholileyo nengena umoya.Zigcine kude nomlilo kunye nobushushu.Ubushushu bokugcina akufunekanga budlule kwi-30 ℃.Gcina izitya zivaliwe.Iya kugcinwa ngokwahlukileyo kwi-oxidants, i-acids, i-alkali kunye neekhemikhali ezidliwayo, kunye nokugcinwa okuxutywayo akuyi kuvunyelwa.Akufanele igcinwe ngobuninzi okanye ixesha elide.Izibane ezikhusela uqhushumbo kunye neendawo zokungenisa umoya ziya kwamkelwa.Akuvumelekanga ukusebenzisa izixhobo zoomatshini kunye nezixhobo ezilula ukuvelisa iintlantsi.Indawo yokugcina iya kuxhotyiswa ngezixhobo zonyango olungxamisekileyo oluvuzayo kunye nezixhobo ezifanelekileyo zokufumana.Inkqubo yokulawula "izibini ezihlanu" kwizinto eziyityhefu kakhulu iya kuphunyezwa ngokungqongqo.
V. Ukudibana kwesikhumba: khulula iimpahla ezingcolileyo ngokukhawuleza kwaye uhlambe ngamanzi amaninzi ahambayo ubuncinane imizuzu eyi-15.Funa unyango.
Vi.ukudibana neeglasi: phakamisa iinkophe ngokukhawuleza kwaye uhlambe ngokucokisekileyo ngamanzi amaninzi ahambayo okanye i-saline eqhelekileyo ubuncinane imizuzu eyi-15.Funa unyango.
VII.Ukuphefumla: shiya ngokukhawuleza indawo kwindawo enomoya omtsha.Gcina iphecana lokuphefumla lingaphazamiseki.Ukuba ukuphefumla kunzima, nika ioksijini.Ukuba ukuphefumla kuyeka, mnike ukuphefumla okufakelweyo ngoko nangoko.Funa unyango.8, Ukungeniswa: hlambulula ngamanzi kwaye usele ubisi okanye iqanda elimhlophe.Funa unyango.
IX.ukukhuselwa kwenkqubo yokuphefumla: xa ugxininiso emoyeni ludlula umgangatho, kufuneka unxibe imaski yegesi yokucoca i-self-priming (imaski epheleleyo).Kwimeko yohlangulo olungxamisekileyo okanye ukufuduswa, isiphefumlo somoya siya kunxitywa.
X. ukukhuselwa kwamehlo: inkqubo yokuphefumla ikhuselwe.
Xi.Ukukhuselwa kwesandla: nxiba iiglavu zerabha.
XII.Unyango lokuvuza: khupha abasebenzi kwindawo evuzayo kwindawo engcolileyo ngokukhawuleza, ubabeke bodwa, uthintele ngokungqongqo ukufikelela kwaye unqumle umthombo womlilo.Kwenziwa isincomo sokuba abasebenzi bonyango olungxamisekileyo banxibe isixhobo sokuphefumla esinoxinzelelo olulungileyo kunye nempahla echasene netyhefu.Sika umthombo wokuvuza kangangoko.Thintela ukuba ungampompozi kwiindawo ezithintelweyo ezifana nemijelo ephantsi komhlaba ehambisa amanzi amdaka kunye nemisele yogutyulo.Ukuvuza okuncinci: Ukufunxa ngekhabhoni esebenzayo okanye isanti.Inokuphinda ihlanjwe ngamanzi amaninzi, ihlanjululwe ngamanzi okuhlamba kwaye ifakwe kwisistim samanzi amdaka.Inkunkuma iya kuhanjiswa isiwe kwindawo ekhethekileyo yokulahla inkunkuma.
