Kugwiritsa Ntchito Mapaipi Apulasitiki
Monga gawo lofunikira la zida zomangira mankhwala, mapaipi apulasitiki amavomerezedwa ndi ogwiritsa ntchito chifukwa cha magwiridwe antchito awo apamwamba, ukhondo, chitetezo cha chilengedwe, mowa wotsika ndi zabwino zina, makamaka kuphatikiza chitoliro cha UPVC, chitoliro chamadzi cha UPVC, chitoliro cha aluminium pulasitiki, polyethylene ( PE) chitoliro chamadzi, chitoliro chamadzi otentha cha polypropylene PPR.
Mapaipi apulasitiki ndi zida zomangira mankhwala zophatikizidwa ndiukadaulo wapamwamba, ndipo zida zomangira mankhwala ndi mtundu wachinayi womwe ukutuluka wazinthu zomangira zatsopano pambuyo pa chitsulo, matabwa ndi simenti.Mipope ya pulasitiki imagwiritsidwa ntchito kwambiri pomanga madzi ndi ngalande, madzi a m'tawuni ndi ngalande ndi mapaipi a gasi chifukwa cha ubwino wawo wa kutaya madzi pang'ono, kupulumutsa mphamvu, kupulumutsa zinthu, kuteteza zachilengedwe, kumaliza bwino ndi zina zotero, ndipo akhala. mphamvu yaikulu ya mizinda yomanga chitoliro maukonde m'zaka za zana latsopano.
Poyerekeza ndi miyambo kuponyedwa chitsulo mipope, kanasonkhezereka zitsulo mipope, simenti mipope ndi mipope ena, mapaipi pulasitiki ndi ubwino kusungira mphamvu ndi kupulumutsa chuma, kuteteza chilengedwe, kulemera kuwala ndi mphamvu mkulu, kukana dzimbiri, yosalala mkati khoma popanda makulitsidwe, zomangamanga yosavuta ndi kukonza, moyo wautali wautumiki ndi zina zotero.Amagwiritsidwa ntchito kwambiri pomanga, ma municipalities, mafakitale ndi minda yaulimi monga kumanga madzi ndi ngalande, madzi akumidzi ndi kumidzi, gasi wam'tawuni, magetsi ndi kuwala kwa chingwe, kufalitsa madzimadzi a mafakitale, ulimi wothirira ndi zina zotero.
Pulasitiki ndi yosiyana ndi zipangizo zachikhalidwe.Liwiro la kupita patsogolo kwaukadaulo kuli mwachangu.Kutuluka kosalekeza kwa matekinoloje atsopano, zipangizo zatsopano ndi njira zatsopano kumapangitsa ubwino wa mapaipi apulasitiki kukhala otchuka kwambiri poyerekeza ndi zipangizo zamakono.Poyerekeza ndi chitoliro chachitsulo chachitsulo ndi chitoliro cha simenti, chitoliro cha pulasitiki chimakhala cholemera, chomwe nthawi zambiri chimakhala 1/6-1/10 cha chitoliro chachitsulo.Ili ndi kukana bwino kwa dzimbiri, kukana kwamphamvu komanso kulimba kwamphamvu.Pakatikati pa chitoliro cha pulasitiki ndi chosalala kwambiri kuposa chitoliro chachitsulo choponyedwa, chokhala ndi mikangano yaying'ono komanso kukana madzimadzi.Itha kuchepetsa kugwiritsa ntchito mphamvu zotumizira madzi ndi 5%.Ili ndi chitetezo chokwanira champhamvu, ndipo kugwiritsa ntchito mphamvu zamagetsi kumachepetsedwa ndi 75%.Ndi yabwino kunyamula, yosavuta kukhazikitsa, ndipo moyo wake wautumiki ndi zaka 30-50.Mipope ya polyethylene yakula kwambiri padziko lapansi, ndipo mayiko otukuka ali ndi mwayi wogwiritsa ntchito mapaipi a polyethylene popereka madzi ndi gasi.Mipope ya polyethylene sikuti imagwiritsidwa ntchito kwambiri m'malo mwa mipope yachitsulo yachikhalidwe ndi mapaipi achitsulo, komanso m'malo mwa mapaipi a PVC.Chifukwa chagona luso luso mapaipi polyethylene.Kumbali ina, nkhanizo zapita patsogolo kwambiri.Kupyolera mu kusintha kwa polyethylene polymerization ndondomeko kupanga, mphamvu ya polyethylene chitoliro chakuthupi wapadera pafupifupi kawiri.Komano, pali chitukuko chatsopano mu umisiri ntchito, monga luso kuyala mipope polyethylene ndi njira kubowola njira popanda kukumba ngalande chitoliro, amene amapereka kusewera kwathunthu ubwino wa mipope polyethylene, kuti mipope chikhalidwe alibe mpikisano nthawi zina. oyenera njira iyi.Palinso zida zambiri zatsopano ndi matekinoloje omwe akuphunziridwa, kapena aphunziridwa ndikuyesedwa.Ndizosakayikitsa kuti kupita patsogolo kwaukadaulo kwa mapaipi apulasitiki m'zaka 10 zikubwerazi kudzalimbikitsa chitukuko chofulumira komanso kugwiritsa ntchito mapaipi apulasitiki ambiri.
