Silicone ndi chinthu chosinthika kwambiri chomwe chimagwiritsidwa ntchito m'mafakitale angapo.Silicone imapezeka muzinthu zomwe timagwiritsa ntchito pamoyo wathu watsiku ndi tsiku, kuchokera pamagalimoto omwe timayendetsa, kukonza chakudya ndi zinthu zosungirako, mabotolo a ana ndi pacifiers, ndi mano ndi zinthu zina zaukhondo za tsiku ndi tsiku.Silicone imagwiritsidwanso ntchito kwambiri pazinthu zomwe zingapulumutse miyoyo yathu kuphatikiza masks opumira, ma IV, ndi zida zina zofunika kwambiri zachipatala ndi zaumoyo. M'nkhaniyi, tikambirana momwe angagwiritsire ntchito komanso momwe amafananizira ndi silicon ndi pulasitiki.Muphunzira zambiri za kapangidwe ka silicone ndi zina mwazabwino zapawiriyi.

Kodi Silicone N'chiyani?

Silicone, yomwe imadziwikanso kuti polysiloxane, ndi zinthu zopangidwa ndi anthu.Ndi polima yopangidwa ndi siloxane yomwe imakhala ngati mphira yofanana ndi mamolekyu omwe ali ndi unyolo wa ma atomu a oxygen ndi silicon.Polima yapaderayi ikhoza kukhala chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito mu:

• Ma resin
• Madzi
• Elastomers

Chosiyanitsa chosiyana pakati pa silikoni ndi ma polima ena ogulitsa mafakitale ndikuti msana wawo wa cell ulibe mpweya.Zina mwazinthu zomwe zimagwiritsidwa ntchito pa silicone ndi izi:

• Chipinda chodyera cha silicone
• Silicone zodzoladzola brush
• Zakhitchini
• O-mphete
• mphasa yosamva kutentha
• Silicone mwana teether
• Zoumba zosinthika
• Zoseweretsa zamaphunziro za silicone
• Gaskets
• Silicone collapsible Makapu
• Ketulo yopinda
• Silicone pet mbale
• Ana kudyetsa pacifier

Mafakitale kuyambira zamagalimoto kupita ku nsalu ndi ogula kupita ku chipatala amagwiritsa ntchito silikoni pazifukwa zosiyanasiyana.

Kodi Silicone Amapangidwa Ndi Chiyani?

Monga polima wosunthika, silicone ili motere:

• Caulks
• Mafuta
• Elastomers
• Mafuta

Chofunikira chachikulu mu silikoni ndi silika - imodzi mwamchenga womwe umapezeka kwambiri.Izi ndi zomwe muyenera kudziwa za silikoni motsutsana ndi silicon.

Kodi Silicone Imapangidwa Bwanji?

Tiyeni tifufuze njira zosiyanasiyana zopangira silicone.

Khwerero 1: Sungani Silicon Kuchokera ku Silika

Kupatula silicon ku silika ndiye gawo loyamba popanga silikoni.Kuti akwaniritse izi, mchenga waukulu wa quartz umatenthedwa mpaka kutentha mpaka madigiri 1800 Celsius.Silicon yoyera, yodzipatula ndiyo zotsatira zake.Ukazizira, opanga amatha kuwupera kukhala ufa wosalala.

Khwerero 2: Phatikizani ufa Ndi Methyl Chloride

Ufa wabwino wa silicon umasakanizidwa ndi methyl chloride.Kupakanso kutentha kumayambitsanso kuchitapo kanthu pakati pa zigawo zomwe zimapanga zomwe zimadziwika kuti methyl chlorosilane.Methyl chlorosilane ndi kusakaniza komwe kumakhala ndi mankhwala angapo, omwe ambiri, dimethyldichlorosilane, ndiye maziko omanga a silicone.

Khwerero 3: Distill Mix

Kuchokera ku dimethyldichlorosilane kupita ku silikoni kumafuna njira yovuta ya distillation kuti alekanitse zigawo zosiyanasiyana za methyl chlorosilane kuchokera kwa wina ndi mnzake.Chifukwa ma chlorosilanes ali ndi zowiritsa zosiyanasiyana, sitepe iyi imaphatikizapo kutenthetsa kusakaniza mpaka kuzizira koyenera.

Khwerero 4: Kuwonjezera Madzi

Kutsatira distillation, kuphatikiza madzi ndi dimethyldichlorosilane kumayambitsa kulekana kwa hydrochloric acid ndi disilanol. Hydrochloric acid ndiye imagwira ntchito ngati chothandizira diquinone, ndikupangitsa kuti ikhale polydimethylsiloxane.

Khwerero 5: Polymerization ya Silicone

Mudzazindikira kuti polydimethylsiloxane ili ndi chomangira cha siloxane.Chomangira ichi ndi msana wa silikoni.Polymerizing silicone imaphatikizapo njira zingapo kutengera zomwe zamalizidwa zomwe mukufuna. Ngakhale kupanga silikoni kungawoneke ngati kovuta, kwenikweni, ndikosavuta ndipo kumatha kuchitika pamlingo wokwera mtengo wotsika.Chifukwa chake, ndizosadabwitsa kuti silikoni yosunthika yatuluka ngati imodzi mwama elastomers otchuka kwambiri pazamalonda ndi mafakitale.

Silicone vs. Pulasitiki

Pulasitiki ndi silikoni ndizolimba kwambiri komanso zosinthika, ndipo zimatha kukhala ndi mawonekedwe ofanana.Ngakhale kuti ziŵirizo zimafanana kwambiri, makhemikolo ndi mamolekyu awo amapangidwa mosiyanasiyana. Pulasitiki ili ndi msana wa mamolekyu wopangidwa ndi carbon ndi hydrogen.Kupanga iwo kumagwiritsa ntchito zinthu zotsatirazi:

• Gasi wachilengedwe
• Zomera
• Mafuta akuda

Pulasitiki amapangidwa kuchokera ku zinthu zosakonda zachilengedwe ndipo amatha kusweka kukhala ma microplastic owopsa.Komanso nthawi zina amakhala ndi poizoni, monga bisphenol A. Pulasitiki sakhalitsa ngati silikoni ndipo sagonjetsedwa ndi kutentha kwambiri.

Ubwino wa Silicone

Zida za silicone ndizothandiza kwambiri pazinthu zosiyanasiyana.Chifukwa cha katundu wake, silikoni zipangizo zili ndi ubwino wambiri, katundu ndi awa:

• Kusinthasintha
• Malleability
• Kumveka bwino
• Kutentha kukana
• Kukana madzi
• Kuthekera kwa mpweya
• Kukhalitsa
• Zosavuta kuyeretsa
• Wopanda ndodo
• Zosapaka banga
• Mpweya wochuluka kwambiri
• Zokhalitsa
• Zopanda poizoni
• Zosanunkhiza

Silicone ndiyosavuta kusintha ndi kuumba ndipo imabwera m'njira zosiyanasiyana (zamadzimadzi, zolimba kapena pepala) kutengera momwe amapangira kapena kupanga ndikugwiritsa ntchito mwapadera.Kaya ntchito yanu ikufuna kukana kutentha kwambiri kapena kusasinthika, opanga zinthu amapereka mitundu yosiyanasiyana yamagulu ndi magiredi kuti akwaniritse zosowa zanu zosiyanasiyana.
