Chii chinonzi PBT uye Nei Ichishandiswa Zvakawanda?
Polybutylene Terephthalate (PBT) ndeyepamusoro-inoshanda engineering thermoplastic yakagadzirwa kubva kubutylene glycol uye terephthalic acid, ine zvimiro zvakafanana nePolyethylene Terephthalate (PET). Senhengo yemhuri yepolyester, PBT inoshandiswa zvakanyanya mumotokari, zvemagetsi, uye zvikamu zvehutsanana nekuda kwesimba rayo remakina emagetsi, kugadzikana kwakanyanya kwemafuta, kuvharwa kwemagetsi, kuramba makemikari, uye unyoro. Aya mabhenefiti anoita kuti ive chinhu chakasarudzika chekubatanidza, dzimba, uye emukati ma trims.
Sei Zvinetso Zvepamusoro muPBT Zvichive Kunetseka Kunokura muPamusoro-Kupera Maindasitiri Zvikumbiro?
Semaindasitiri akaita semotokari, zvemagetsi, uye huinjiniya hwakasimba hunosimudza chitarisiko chenyama uye kusimba, Polybutylene Terephthalate (PBT) -injiniya inoshandiswa zvakanyanya purasitiki - inotarisana nekumanikidza kuunza hunyoro hwepamusoro.
Pasinei nekusimba kwayo kwemagetsi uye kupisa chimiro, PBT inotapukirwa nekuremara kwepamusoro panguva yekugadziriswa-kunyanya kana yaiswa mukupisa, shear, kana unyoro. Izvi zvinokanganisa zvakananga kwete kwete chete chitarisiko chechigadzirwa asiwo kushanda kuvimbika.
Zvinoenderana nedata reindasitiri, izvo zvinonyanya kukanganisa pamusoro pezvigadzirwa zvePBT zvinosanganisira:
• Silver Streaks/Maki Emvura: Kukanganisa kuoneka se radial mapatani pachigadzirwa chinokonzerwa nehunyoro, mweya, kana carbonized material zvichitevera kuyerera
• Mhepo Marks: Kunyungudika kana mabubbles anoumbwa kana magasi ari mukunyunguduka atadza kubuda zvachose.
• Flow Marks: Mapeteni epamusoro anobva mukuyerera kwezvinhu zvisina kuenzana
• Orange Peel Effect: Musoro wepamusoro wakafanana neganda reorenji
• Surface Scratches: Kukuvadzwa kwepamusoro kunokonzerwa nekukwesha panguva yekushandiswa
Izvi zvinokanganisa hazvingokanganisa chigadzirwa aesthetics asi zvinogona kutungamira kune zvinoshanda. Matambudziko ekukwenya kwepamusoro akanyanya kusimba mune dzepamusoro-yekupedzisira mota dzemukati uye zvemagetsi zvevatengi, nehuwandu hunoratidza kuti vanopfuura makumi matanhatu neshanu muzana evatengi vanoona kuramba kwekutanga chiratidzo chakakosha kana vachiongorora mhando yechigadzirwa.
Vagadziri vePBT Vanogona Sei Kukunda Aya Matambudziko Akaremara?Material Formulation Innovation!
Composite Modification Technology:BASF ichangoburwa Ultradur® Yepamberi yakatevedzana PBT zvinhu zvinoshandisa hunyanzvi hwekugadzirisa zvinhu zvakasiyana-siyana, zvinonyanya kuwedzera kuoma kwepasi uye kuramba kwekukwenya nekuunza zvikamu zvakati zvePMMA muPBT matrix. Data yekuedza inoratidza kuti zvinhu izvi zvinogona kuwana kuomarara kwepenzura ye1H-2H, inodarika 30% yakakwirira kupfuura yechinyakare PBT.
Nano-Enhancement Technology:Covestro yakagadzira nano-silica yakakwidziridzwa PBT maumbirwo ayo anowedzera kuomarara kwepasi kusvika ku1HB nhanho uku achichengetedza zvinhu zviri pachena, zvichivandudza kuramba kwekukwenya neanenge 40%. Iyi tekinoroji inonyanya kukodzera mukati memotokari yemukati uye yepamusoro-yekupedzisira zvigadzirwa zvemagetsi zvigadzirwa zvine kuomarara kutaridzika zvinodiwa.
Silicone-based Additive Technology:Kuti agadzirise nyaya idzi dzinokosha, SILIKE, mutungamiri anotungamira mu polymer additive technology, akagadzira podfolio ye siloxane-based additive solutions yakagadzirirwa zvakananga PBT uye mamwe thermoplastics.Izvi zvinowedzera zvinogadzirisa zvinotarisa zvikonzero zvinokonzera kukanganisa kwepamusoro uye kuvandudza zvose kugadzirisa kushanda uye kusimba kwechigadzirwa.
SILIKE's Silicone-based Additive Solutions for Enhanced PBT Surface Quality
Silicone Masterbatch LYSI-408 inogadzirwa nepelletized ine 30% yepamusoro mamorekuru huremu siloxane polymer yakaparadzirwa mupolyester (PET). Iyo inoshandiswa zvakanyanya seyakawedzera inoshanda yePET, PBT, uye inoenderana resin sisitimu yekuvandudza zvivakwa zvekugadzirisa uye pamusoro pemhando.
Mabhenefiti akakosha ekugadzirisa anowedzera LYSI-408 yePBT engineering epurasitiki:
• Inosimudzira kuyerera kweresin, kusunungurwa kwe mold, uye kupera kwepamusoro
• Inoderedza extruder torque uye kukwesha, kuderedza kukwenya kuumbwa
• Chimiro chekutakura: 0.5-2 wt%, yakagadziridzwa yekushanda / mutengo wemari
2. Silicone Wax SILIMER 5140: Polyester-Modified Silicone Additive in Engineering Thermoplastics
SILIMER 5140 ndeye polyester yakagadziridzwa silicone yekuwedzera ine yakanakisa kupisa kugadzikana. Inoshandiswa muzvigadzirwa zve thermoplastic zvakadai sePE, PP, PVC, PMMA, PC, PBT, PA, PC/ABS, etc. Zvinogona Zviripachena kuvandudza zvigadziriswe zvinodzivirira uye kusapfeka-resistant pamusoro pezvinhu zvezvigadzirwa, kuvandudza lubricity uye mold kusunungurwa kwemaitiro ekugadzirisa zvinhu kuitira kuti chigadzirwa chive nani.
Mabhenefiti akakosha eSilicone Wax SILIMER 5140 yePBT engineering epurasitiki:
• Inopa kugadzikana kwemafuta, kukwenya & kusakara, uye kunyorova kwepamusoro
• Inovandudza kuumbwa uye inowedzera hupenyu hwechikamu
Kutarisa Kubvisa Kukanganisa Kwepamusoro, kuwedzera chigadzirwa aesthetics, uye kuwedzera PBT Chigadzirwa Kuita?
Kune maOEMs nemacompounders mumaindasitiri emotokari, zvemagetsi, uye nemapurasitiki chaiwo, kushandisa siloxane-based plastic additive inzira yakasimbiswa yekugadzirisa matambudziko ekugadzira uye kuwedzera kunaka kwepamusoro uye kuramba muPBT. Iyi nzira inobatsira kusangana nekuwedzera kwemusika zvinotarisirwa.
SILIKE ndiye anotungamira mupi weakagadziridzwa epurasitiki ekuwedzera ePBT uye yakafararira thermoplastics, ichipa zvigadziriso zvekuvandudza mashandiro uye kushanda kwemidziyo yepurasitiki. Neanopfuura makore makumi maviri eruzivo rweindasitiri, isu tinonyanya kugadzira nekugadzira zvemhando yepamusoro zvekuwedzera izvo zvinovandudza mhando yepamusoro, uye kugadzirisa zvivakwa zvepurasitiki.
Bata SILIKE kuti uone kuti yedu PBT yekuwedzera mhinduro inogona kukubatsira sei kukwidziridza mhando yechigadzirwa uye kugadzirisa kunyatsoshanda-inotsigirwa nehunyanzvi hwedu hwehunyanzvi uye yakarongedzwa application rutsigiro.
