Iimbonakalo:I-RE yi-arhente edibanisayo esebenza kakhulu, esetyenziswa kwi-adhesives eyenziwe yi-hydroxyl polyurethane, irabha yendalo okanye yokwenziwa,
Inamandla okudibanisa okugqwesileyo kwirabha kunye nekhabhu esetyenziselwa i-resin, i-antioxidant, i-agent ye-plasticizing, i-pressure-sensitive njl.
Ingasetyenziswa njenge-crosslinker endaweni ye-BAYER's Desmodur RE.
Ukusetyenziswa:I-adhesive-component component kufuneka isetyenziswe ngaphakathi kwexesha elisebenzayo emva kokubeka i-RE.
Ubude bexesha elisebenzayo abuhambelani kuphela nomxholo we-polymer wokunamathela, kodwa kunye namanye amacandelo afanelekileyo (njenge-resin, i-antioxygen, i-plasticizer, i-solvent, njl.
Xa kusondele ixesha elifanelekileyo, ngokuqhelekileyo iiyure ezimbalwa okanye usuku olunye lokusebenza, i-adhesive iba nzima kakhulu ukusebenza, kwaye i-viscosity iphakama ngokukhawuleza.
Ekugqibeleni, Iba yijeli engenakuguquleka.I-adhesive yekhwalithi ye-100, i-Hydroxyl polyurethane (i-akhawunti ye-Polyurethane malunga ne-20%), i-RE dose ye-4-7.I-rubber ye-chloroprene (i-akhawunti ye-Rubber malunga ne-20%), i-RE yenza i-4-7.
Ugcino:Nceda ugcinwe kwingqayi yokuqala etywiniweyo phantsi kwe-23 ℃, iimveliso zinokugcinwa zizinzileyo kwiinyanga ezili-12.Inomdla kakhulu kubuninzi;iya kuvelisa i-carbon dioxide kunye ne-urea enganyibilikiyo ekuphenduleni ngamanzi.Ukuba ukuvezwa emoyeni we-teh okanye ukukhanya, kuya kukhawulezisa utshintsho lombala, kodwa umsebenzi osebenzayo awuyi kuchaphazeleka.
Ukwengeza: Inkampani inokuphanda kwaye iphuhlise iimveliso ezintsha ngokwemfuno ekhethekileyo yabathengi bethu.
Ukuchongwa kweengozi
Ulwahlulo lweGHS:
Ulwelo olunokutsha, Udidi 2 (H225)
Ubutyhefu obubukhali, ukuphefumla, udidi 4 (H332)
Ukucaphuka kolusu, udidi 2 (H315)
Ukucaphuka kwamehlo, udidi 2 (H319)
Ukuqonda iindlela zomoya zokuphefumla, udidi 1 (H334)
Ukuqonda ulusu, udidi 1 (H317)
Ityhefu ethile ekujoliswe kuyo (uvelwano olunye), udidi 3 (H335) (H336)
GHS-iLebhile:
Amalungu anobungozi ekufuneka adweliswe kwileyibhile
i-ethyl acetate
i-triphenylmethane-4,4',4''-triisocyanate
Iingxelo zengozi:
H225 Ulwelo olunokutsha kakhulu kunye nomphunga.
H315 Ibangela ukucaphuka kwesikhumba.
I-H317 Inokubangela ukusabela kolusu.
H319 Ibangela ukucaphuka kwamehlo okunzulu.
H332 Kuyingozi ukuba utsaliwe.
I-H334 Isenokubangela ukungezwani komzimba okanye iimpawu zombefu okanye ubunzima bokuphefumla ukuba uthe waphefumla.
I-H335 Inokubangela ukucaphuka kokuphefumla.
H336 Inokubangela ukozela okanye isiyezi.
Iingxelo zokhuseleko:
P210 Zigcine kude nobushushu/iintlantsi/amadangatye avulekileyo/imiphezulu eshushu.- Akutshaywa.
P280 Nxiba iiglavu ezikhuselayo/ iimpahla ezikhuselayo/ ukhuseleko lwamehlo/ ukhuseleko lobuso.
P303 + P361 + P353 UKUBA ELUSU (okanye iinwele): Susa/ Khulula ngoko nangoko zonke iimpahla ezingcolisekileyo.Sula ulusu ngamanzi/ishawa.

P304 + P340 UKUBA INHALED: Susa ixhoba emoyeni omtsha kwaye uhlale uphumle kwindawo ekhululekile yokuphefumla.
P312 Biza iPOISON CENTRE okanye ugqirha/ ugqirha ukuba uziva ungaphilanga.
P403 + P233 Gcina kwindawo engenamoya.Gcina isikhongozeli sivalwe ngokuqinileyo.
I-P501 Ukulahla iziqulatho / isikhongozeli ngokuhambelana nommiselo wendawo.
