Shenhai Kuphulika-Umboni
Tanthauzo
Chitetezo cha kuphulika, kalasi ya kutentha, mtundu wachitetezo cha kuphulika, ndi kuyika chizindikiro m'malo ofunikira ndizofunikira pakuwunika zida zamagetsi zomwe sizingaphulike. Chidziwitsochi chimagwiritsidwa ntchito kufotokoza mlingo wa chitetezo kuphulika, kuchuluka kwa kutentha komwe zida zimatha kugwira ntchito bwino, mtundu wa chitetezo cha kuphulika choperekedwa, ndi madera omwe adasankhidwa pomwe zida ndizoyenera.

Chizindikiro ichi chikuwonetsa kuti zida zamagetsi zimakumana ndi mitundu imodzi kapena zingapo zophulika mu miyezo yophulika;
Malinga ndi zomwe zafotokozedwazo 29 wa GB3836.1-2010 muyezo, Ndizofunikira zida zamagetsi zosaphulika kunyamula chosiyana “Eks” kuyika malo otchuka pathupi la kunja kwake. Kuphatikiza apo, Dongosolo la zida liyenera kuwonetsa chitsimikizo chogwiritsira ntchito mogwirizana ndi chitsimikizo chomwe chimatsimikizira
kukhutisidwa.

Zindikirani: Gome likuwonetsa mtundu woteteza zachilengedwe poteteza zida zamagetsi, Kuwonetsa kuphatikiza kwa njira zosiyanasiyana zotetezera kuti apange mitundu yoteteza zoteteza.
Mwachitsanzo, Mayina “Ex demb” imayimira mtundu wophatikiza wophulika kwa zida zamagetsi, kuphatikiza osayaka moto, kuchuluka kwa chitetezo, ndi njira za encapsulation.
Gulu la madera omwe amapezeka pamtunda wamagetsi:
M'madera omwe mpweya wophulika ndi kuyaka Mimbulu imaphatikiza ndi mpweya kuti apange masiketi ophulika, magawo atatu oyang'anira kutengera kuchuluka kwa ngozi yakhazikitsidwa:
Zone 0 (amatchedwa one 0): Malo omwe masitolo osakanizira mosalekeza, kambirimbiri, kapena molunjika nthawi zambiri.
Zone 1 (amatchedwa one 1): Malo omwe mitundu yosakaniza magesi imatha kuchitika nthawi zonse.
Zone 2 (amatchedwa one 2): Malo omwe zosakaniza zamagetsi sizikuyembekezeka kuzimiririka, Koma zitha kungowoneka pang'onopang'ono pamachitidwe achipongwe.
Zindikirani: Zinthu zabwinobwino zimangotanthauza kuyamba kokhazikika, Tsekani, ntchito, ndi kukonza zida, Pomwe mikhalidwe yoyipa imakhudza zida zovomerezeka kapena
machitidwe ozindikira.
Kuphatikiza pakati pa madera omwe ali pachiwopsezo cha kuphulika kwa mpweya ndi mitundu yolingana ndi zotsatira.

Gulu la gasi la chipangizo cha madzi ophulika chimatsimikiza kugwirizana kwake ndi zosakaniza zamagesi.
Kutanthauzira kwa gulu la mpweya:
M'madera onse ophulika, kupatula migodi ya malasha ndi madera obisika (i.e., madera oyenererana ndi zida zamagetsi), Magesi ophulika amagawidwa m'magulu atatu, ndiye, B, ndi C, Kutengera njira yoyesera yoyeserera kapena kuyika pang'ono kuchuluka kwa zinthu zosakaniza zamagesi. Kutentha kwa mpweya komanso kutentha kutentha kumadalira kwa gasi woyaka ndi mpweya pansi pa kutentha kwachilengedwe ndi mikhalidwe yokakamizidwa.
Ubale pakati pa zosakaniza za mafuta, Magulu a Magulu, ndi zoyeserera zoyeserera kwambiri kapena kuyika pang'ono pazigawo zamakono:
