Ndi kukhazikitsidwa kwa Mapulani a Zaka 12 a Zaka zisanu, ntchito yotukula mizinda ya dziko langa idzapita patsogolo chaka ndi chaka.Kuwonjezeka kulikonse kwa 1% pakukula kwa mizinda kudzafuna ma cubic metres 3.2 biliyoni a madzi akumatauni.Choncho, linanena bungwe mipope pulasitiki akadali akuyembekezeka kusunga avareji mlingo wa 15%.Kukula kophatikizana pafupifupi%.

Mapaipi apulasitiki aku China apanga gulu lofunikira lazinthu zamapulasitiki.Zipangizo zomangira mankhwala ndi mtundu wachinayi wa zida zomangira zatsopano zomwe zikutuluka masiku ano pambuyo pa chitsulo, matabwa, ndi simenti.Mipope ya pulasitiki, mbiri ya pulasitiki, zitseko ndi mawindo ndi mitundu iwiri ikuluikulu ya zipangizo zomangira mankhwala zomwe zimagwiritsidwa ntchito kawirikawiri.Kuyambira 1994, boma la China lakhala likugwirizana ndi Unduna wa Zomangamanga, unduna wakale wa Chemical Viwanda, womwe kale unali China National Light Viwanda Council, National Building Materials Bureau, ndi wakale China Petrochemical Corporation kuti akonzekere "National Chemical. Building Materials Coordination Leading Group” kuti apange ndi kufalitsa zoyesayesa zoyenera.Kupititsa patsogolo zolinga za zipangizo zomangira mankhwala, ndondomeko, ndondomeko, miyezo, ndi zina zotero. Zaka zingapo chabe, mapaipi apulasitiki a China, mbiri, zitseko ndi mazenera apeza chitukuko chofulumira.The dziko mphamvu yopanga mipope pulasitiki mu 1994 anali 240,000 matani, ndipo linanena bungwe anali 150,000 Mu 2000, mphamvu anali matani 1.64 miliyoni, ndi linanena bungwe anali 1 miliyoni matani (amene linanena bungwe mapaipi PVC-U anali za matani 500,000) , mzere wopanga chitoliro wafika kuposa 2,000, ndipo kukula kwakukulu kwa mapaipi olimba a polyvinyl chloride ndi matani oposa 10,000.Pali mabizinesi opitilira 30 m'dziko lonselo.

Maukonde achitoliro achikhalidwe amakhala makamaka mapaipi achitsulo, mapaipi achitsulo, mapaipi a simenti ndi mapaipi adongo.Traditional chitoliro zipangizo zambiri makhalidwe a mowa mkulu mphamvu ndi kuipitsa chilengedwe.Panthawi imodzimodziyo, maukonde a chitoliro alinso ndi zofooka zotsatirazi: ① Moyo waufupi wautumiki, nthawi zambiri zaka 5-10;②Kusagwira bwino kwa mankhwala ndi kukana dzimbiri;③Kuwonongeka kwa hydraulic;④Kumanga kwakukulu, nthawi yayitali;⑤Kusalungama kwa mapaipi, kutsika kosavuta, ndi zina zambiri. Kuyambira pakati pa zaka za m'ma 1900, mayiko padziko lonse lapansi, makamaka mayiko otukuka, akhala akupanga zida zapadera zamapaipi apulasitiki ndikugwiritsa ntchito mapaipi apulasitiki.

M’zaka khumi zapitazi, mapaipi apulasitiki apangidwa mofulumira.Mapaipi apulasitiki akuchulukirachulukirachulukirachulukira chifukwa choteteza chilengedwe komanso chitetezo m'moyo watsiku ndi tsiku komanso ntchito zamafakitale, ndipo amatenga gawo lofunikira komanso losasinthika.Makamaka m'makampani omanga, mapaipi apulasitiki sangangosintha zitsulo, nkhuni, ndi zida zomangira zamtundu wambiri, komanso amakhala ndi mwayi wopulumutsa mphamvu, kupulumutsa zinthu, kuteteza zachilengedwe, kuwongolera malo okhala, kuwongolera ntchito yomanga. ndi ubwino, kuchepetsa kulemera kwa nyumba, ndi kumaliza bwino., Amagwiritsidwa ntchito kwambiri pomanga madzi ndi ngalande, madzi am'tawuni ndi ngalande, mapaipi a gasi ndi minda ina;kukula kwa mipope ya pulasitiki ndi pafupifupi nthawi 4 kukula kwa mipope, yomwe ndi yokwera kwambiri kuposa kukula kwa chuma cha dziko la mayiko osiyanasiyana.Kusintha mapaipi achitsulo ndi mipope yachitsulo yokhala ndi mipope yapulasitiki yobiriwira yobiriwira yakhala njira yachitukuko m'zaka zatsopano.Mipope ya pulasitiki yapangidwa bwino ndikugwiritsidwa ntchito kwambiri m'mayiko otukuka, makamaka ku Ulaya;chitukuko m'dziko langa chakhala chikucheperachepera, koma m'zaka zaposachedwa, ndi kupititsa patsogolo mphamvu za dziko langa komanso kupititsa patsogolo moyo wa anthu, mapaipi apulasitiki apita patsogolo mofulumira.mapangidwe a.

Mitundu ndi ntchito za mapaipi apulasitiki zakula mofulumira m'zaka zingapo zapitazi.Pakalipano, mipope ya pulasitiki ya dziko langa yakula kukhala mafakitale omangamanga omwe ali ndi mitundu yosiyanasiyana komanso yochuluka yopangira mphamvu.Mitundu yayikulu yamapaipi apulasitiki ndi: mapaipi a UPVC,CPVC mapaipi, ndi mapaipi a PE., PAP chitoliro, PE-X chitoliro, PP-B chitoliro,PP-R chitoliroPB chitoliro, ABS chitoliro,chitsulo-pulasitiki kompositi chitoliro, galasi CHIKWANGWANI analimbitsa chitoliro, etc. Amagwiritsidwa ntchito mu mipope madzi ndi ngalande mipope yomanga, m'tawuni kukwiriridwa madzi mipope, mipope ngalande, mapaipi mpweya, madzi ndi mipope ngalande kumidzi, mipope ulimi wothirira, ndi zimbudzi mafakitale ndi mayendedwe amadzimadzi amadzi, etc., kukwaniritsa zosowa zamitundu yosiyanasiyana yazachuma chadziko.Zosowa zosiyanasiyana za mapaipi.Tiyenera kupanga ndi kupanga mtundu wina wa chitoliro cha pulasitiki molingana ndi mawonekedwe ndi kugwiritsa ntchito mapaipi osiyanasiyana.
