Zvinosimbisa Musanganiswa weLead
Chinosimbisa simbi cheLead chinhu chinoshandiswa zvakasiyana-siyana chinobatanidza zvinhu zvakawanda zvinobatsira, zvichiita kuti chive sarudzo inotsvakwa mumaindasitiri akasiyana-siyana. Kugadzikana kwaro kwakanyanya kwekupisa kunovimbisa kusimba kwechimiro uye kushanda kwezvigadzirwa zvePVC kunyangwe mumamiriro ekupisa kwakanyanya. Kunyorova kwechinosimbisa simbi kunoita kuti kugadziriswa kuite nyore panguva yekugadzira, zvichiwedzera kushanda zvakanaka kwemaitiro ekugadzira.
Imwe mukana mukuru uri mukusakwanisa kwayo kushandura mamiriro ekunze. Kana zvigadzirwa zvePVC zvikasangana nemamiriro ekunze akasiyana-siyana, lead stabilizer inoita kuti zvirambe zviripo uye chitarisiko chazvo, zvichiita kuti zvikwanise kushandiswa mukati nekunze.
Uyezve, lead stabilizer inoita kuti zvive nyore kushandisa mushonga usina guruva, zvichiita kuti zvive nyore uye zvakachengeteka kuushandisa panguva yekugadzira. Kushanda kwayo kwakasiyana-siyana uye kushandiswa kwakasiyana-siyana kunoita kuti ive yakakodzera kushandiswa kwakasiyana-siyana, zvichibatsira mukushandiswa kwayo zvakanyanya mumaindasitiri akasiyana-siyana.
Panguva yekugadzirisa PVC, chinhu chinosimbisa simbi chinoita basa guru pakuona kuti zvinhu zvacho zvinonyunguduka zvakaenzana uye nguva dzose. Izvi zvinokurudzira kugadzirwa zvakanaka uye zvinobudirira, zvichikonzera zvigadzirwa zvemhando yepamusoro zvine mashandiro akavimbika.
| Chinhu | Zviri Mukati mePb% | ZvinokurudzirwaChipimo chemushonga (PHR) | Kushandiswa |
| TP-01 | 38-42 | 3.5-4.5 | Mapurofayiri ePVC |
| TP-02 | 38-42 | 5-6 | Waya dzePVC netambo |

Pamusoro pezvo, kushandiswa kwemuchina unosimbisa ganda wePVC kunoita kuti zvigadzirwa zvePVC zvirambe zvichikura, zvichiwedzera nguva yazvo yekushanda uye kugara kwenguva refu. Kugona kwemuchina uyu kusimbisa ganda repamusoro kunoita kuti zvigadzirwa zvekupedzisira zvionekwe zvakanaka, zvichiita kuti zvinyanye kukwezva vatengi.
Zvakakosha kuziva kuti chinhu chinosimbisa masero chinofanira kushandiswa nematanho akakodzera ekuchengetedza kudzivirira njodzi dzinogona kuitika pahutano nenharaunda dzine chekuita nemakemikari anobva mumasero. Saka, vagadziri vanofanirwa kutevedzera nhungamiro nemitemo yeindasitiri kuti vave nechokwadi chekuti chinhu ichi chinoshandiswa zvakachengeteka uye zvine mutoro.
Mukupedzisa, lead stabilizer ine zvakanakira zvakasiyana-siyana, kubva pakugadzikana kwekupisa uye kunyorova kusvika pakuramba mamiriro ekunze uye kuwedzera kupenya kwepamusoro. Kusava kwayo neguruva uye kushanda kwayo kwakawanda, pamwe chete nekushanda kwayo zvakanaka, zvinoita kuti ive chinhu chakakosha mukugadzirisa PVC. Zvisinei, zvakakosha kuisa pamberi kuchengetedzeka uye kutevedzera mitemo pakushandisa lead-based stabilizers kuti ive nechokwadi chekuti vatengi nenharaunda vari kugara zvakanaka.
