Iimveliso zePVC zinokwahlulwa zibe ziimveliso ezithambileyo kunye neemveliso ezinzima ngokobulukhuni bazo, kwaye iimveliso ezinzima zisetyenziswa ikakhulu kwimizi-mveliso kunye nezakhiwo.Ngo-2021, iiprofayili, iingcango kunye neeWindows zibalelwa kwi-20% yemfuno iyonke, imibhobho kunye nezinto ezifakelwayo zifikelele kwi-32%, amashiti kunye nezinye iiprofayili zibalelwa kwi-5.5%, ngesikhumba somgangatho, iphepha lodonga, njl.njl. zenze i-7.5%.Ukusuka kulo mlinganiso ungentla, kunokubonwa ukuba ukuchuma kweshishini lezindlu nomhlaba kuhambelana ngokusondeleyo neshishini lePVC.
Iprofayile ye-1.PVC
Ngo-2022, ulwakhiwo lwamashishini eprofayili yasekhaya luphantsi ngokubanzi, kwaye ngokwembono yokulandela ingxelo yeshishini, uluhlu lwempahla lwahlulahlulwe, uluhlu lwempahla ekrwada luphantsi, kwaye uluhlu lwemveliso luphezulu.Izizathu zezi zilandelayo: enye ithathelwa indawo ngamacango e-aluminium ebhulorho ephukileyo kunye neWindows;Okwesibini, kukho iimfuno zokusebenza zokufakelwa kwe-thermal kwibhidi yengingqi;Eyesithathu iyancipha imfuno yaphesheya.
2.PVC umbhobho
Ukuza kuthi ga ngoku, ulwakhiwo lulonke lwamashishini ombhobho alukabi phezulu.Ukwakhiwa komzi-mveliso omkhulu eMzantsi Tshayina kumalunga nesi-5-6 ekhulwini, yaye ukwakhiwa komzi-mveliso omncinane kumalunga nama-40 ekhulwini.EMpuma yeChina naseMntla China, inani lamashishini ombhobho lingaphantsi kwama-50%;KuMbindi wePhondo laseChina laseHunan, apho ukucuthwa kombane kungakhange kuphakanyiswe, ulwakhiwo ngoku luqhuba malunga ne-40%.KwiPhondo laseHubei, apho ukucuthwa kwamandla kuye kwaphakanyiswa kule mpelaveki, ukwakhiwa kunyuke kancinci ukuya kwi-4-5 ekhulwini.Ngokubanzi, ngenxa yemiyalelo ebuthathaka kwi-off-season yemfuno ephantsi, ukwakhiwa akuzange kubuyiselwe kwinqanaba elilindelekileyo, kwaye emva komgubo ophezulu wePVC kunyaka odlulileyo, inxalenye yecala lemfuno ithathelwe indawo yipayipi ye-PE kwindawo. uyilo lomthombo, okwasesinye sezizathu zemfuno ebuthathaka yangoku.Kwixesha elizayo, ngokuhla kweqondo lobushushu kunye nonikezelo oluqinisekisiweyo kwezinye iindawo kwikota yesithathu, imfuno ilindeleke ukuba iphinde ibuyele, kodwa umthamo uwonke unokuthotywa kukuhla koxinzelelo loqoqosho lwehlabathi.
3.PVC umgangatho
Ukususela ngoJanuwari ukuya kuJulayi ka-2022, ukuthunyelwa ngaphandle kweemveliso zomgangatho we-PVC ziphelele kwi-3.2685 yezigidi zeetoni, ukunyuka okunyukayo kwe-4.67% unyaka nonyaka.Nangona ngokuqinisekileyo ukuthunyelwa ngaphandle kweemveliso zomgangatho wePVC kusekho ngaphezulu kwexesha elifanayo kunyaka ophelileyo, kodwa ngokwembono yenyanga, ngoJulayi 2022 izixhobo zasekhaya zePVC ezithumela ngaphandle iitoni ezingama-499,200, ukuhla kwenyanga-ngenyanga kwe-3.24%, ebeke ithemba eliphezulu ekuthunyelweni kumazwe angaphandle kweemveliso zomgangatho ukunika uxinzelelo.Ngokwengxelo evela kumashishini esampula okulandelela i-Longzhong Information, imfuno yasekhaya yamashishini emveliso yomgangatho wehle nge-3-6 ekhulwini, ngelixa i-phenomenon yokurhoxiswa kunye nokuhlehliswa kwemiyalelo yangaphandle yenzekile ukususela ngoJuni, kwaye umyalelo wehla ngo-2. -4 ekhulwini.Ngokwembono yothethathethwano lwangaphandle, iVietnam kunye nezinye iindawo nazo zinokhuphiswano kunye namashishini asekhaya.Amashishini asekhaya ubukhulu becala axhomekeke kwitekhnoloji ephezulu kunye nabathengi bendalo ukuzinzisa iimarike zaphesheya, apho ubuchwephesha obuphambili bamashishini aphakathi kunye namakhulu asekhaya iye yaba yeyona nto iphambili kukhuphiswano lwabo.
Ukushwankathela, ukusuka "ekuqinisekiseni ukuhanjiswa kwezakhiwo" ukuya ekuthotyweni kwenzala ye-asymmetric, ukusebenza kwentlawulo ephantsi yezindlu zasekhaya kuyabonakala, kodwa xa kuthelekiswa nenzala encitshisiweyo, abathengi banenkxalabo malunga necala lonikezelo lokuthembeka kwamashishini ezindlu kunye namandla entengiso. .Ngaphantsi kwemvelaphi yokufudukela ezidolophini kunye nokuguga, amashishini ezindlu nomhlaba asephantsi koxinzelelo olunzima lokunciphisa.Ngokwentelekiso ethatyathwe kwiimveliso zePVC kukho uxinzelelo olunzima lokubuyiswa kwemfuno, ebandakanya ukupheliswa kweemveliso eziqinileyo zePVC, isenzeko sokudibanisa okanye siya kuqhubeka.Njengemveliso yePVC ekrwada ijongene neengxaki zasekhaya nezangaphandle
