Kusanthula kwa zida zazikulu zamapaipi okhala ndi mizere

M'mafakitale amakono, mapaipi okhala ndi mizere amagwiritsidwa ntchito kwambiri mu mankhwala, mafuta, mphamvu zamagetsi, mankhwala ndi mafakitale ena chifukwa cha kukana kwawo kwa dzimbiri, kukana kuvala komanso moyo wautali. Ubwino waukulu wa mapaipi okhala ndi mizere yagona pakusankha zida zawo zomangira. Zida zosiyanasiyana zimatsimikizira zochitika zomwe zikugwiritsidwa ntchito ndi ntchito za mapaipi. Nkhaniyi iwonetsa zida zazikulu ndi mawonekedwe a mapaipi okhala ndi mizere mwatsatanetsatane.

Polyurethane (PU).

Mapaipi okhala ndi mizere ya polyurethane amadziwika chifukwa cha kukana kwawo kuvala bwino komanso kukana kukhudzidwa, ndipo ndi oyenera kutumizira zinthu zowononga kwambiri monga slurry ndi matope. Zida za polyurethane zimakhala ndi mphamvu zambiri ndipo zimatha kuchepetsa mphamvu yamadzimadzi pakhoma lamkati la chitoliro ndikuwonjezera moyo wautumiki wa chitoliro. Kuphatikiza apo, zomangira za polyurethane zilinso ndi kukana kwa dzimbiri kwamankhwala ndipo ndizoyenera kumadera osiyanasiyana amakampani.

Polyethylene (PE).

Mapaipi okhala ndi polyethylene amagwiritsidwa ntchito kwambiri pamankhwala, kuteteza chilengedwe ndi madera ena chifukwa cha kukana kwawo kwa dzimbiri komanso kusinthasintha. Zida za polyethylene zimakhala ndi mankhwala osasunthika ndipo zimatha kukana dzimbiri kuchokera kumitundu yosiyanasiyana ya asidi, alkali ndi mchere wamchere, ndipo ndizoyenera kwambiri kutumiza zakumwa zowononga. Kuphatikiza apo, mapaipi okhala ndi polyethylene ndi opepuka komanso osavuta kukhazikitsa, zomwe zimachepetsa ndalama zomanga.

Polytetrafluoroethylene (PTFE).

Mapaipi okhala ndi polytetrafluoroethylene (PTFE) amadziwika kuti "King of Plastics" ndipo amakhala ndi kukana kwamphamvu kwa dzimbiri komanso kutentha kwambiri. PTFE zakuthupi pafupifupi osasungunuka mu zosungunulira aliyense, akhoza kukana dzimbiri kuchokera zidulo amphamvu, alkali wamphamvu ngakhale aqua regia, ndipo ndi oyenera kwambiri nkhanza mankhwala chilengedwe. Pa nthawi yomweyo, ndi kukangana koyenera wa PTFE alimbane mipope ndi otsika kwambiri, amene angathe kuchepetsa kukana madzimadzi ndi bwino mayendedwe.

Mpira wamiyala

Mapaipi okhala ndi mphira amagwiritsidwa ntchito kwambiri m'migodi, mphamvu ndi mafakitale ena chifukwa cha kulimba kwawo komanso kukana kuvala. Zipangizo za labala zimatha kuyamwa bwino madzimadzi, zimachepetsa kugwedezeka kwa mapaipi ndi phokoso, ndipo ndizofunikira kwambiri kutumizira mauthenga owopsa kwambiri kapena{1}}kuthamanga kwambiri. Zida zopangira mphira wamba zimaphatikizapo mphira wachilengedwe, mphira wa butyl ndi mphira wa chloroprene, ndi zida zosiyanasiyana ndizoyenera magwiridwe antchito osiyanasiyana.

Mapeto

Kusankhidwa kwa zinthu za chitoliro chokhala ndi mizere kumakhudza mwachindunji ntchito yake ndi kuchuluka kwa ntchito. Polyurethane, polyethylene, polytetrafluoroethylene ndi mphira ali ndi ubwino wawo. Mabizinesi amatha kusankha zinthu zoyenera kwambiri zomangira malinga ndi momwe zinthu zimagwirira ntchito kuti zitsimikizire kuyendetsa bwino komanso kukhazikika kwa dongosolo lamapaipi. M'tsogolomu, ndi kupita patsogolo kwa sayansi ya zipangizo, ntchito ya mapaipi okhala ndi mizere idzapitilizidwa bwino, ndikupereka mayankho odalirika a mafakitale osiyanasiyana.
